presents a finite element model for a sandwich plate containing a piezoelectric core. A sandwich plate with a piezoelectric core is constructed using the shear mode of piezoelectric materials. The orientation of poling vector has a significant effect on deflection and stress induced in the piezo-actuated adaptive sandwich plate. In the present study, the influence of this factor for a clamped-clamped-free-free and simple-simple-free-free square sandwich plate is investigated using Finite Element Method. The study uses ABAQUS (v.6.7) software to derive the finite element model of the sandwich plate.

In order to improve the vibrational behavior of the plate, the pseudo‐fibers formed by the effect of the magnetic field on the elastomer charged by the ferromagnetic particles are oriented at 45° with respect to the direction of the magnetic field at 0°. Ritz's approach is taken to solve the physical problem. In order to verify and compare the results obtained by the Ritz approach, an analysis using the finite element method was carried out. The rheological property of the MRE material at 0° and at 45° are determined experimentally, The studied elastomer is prepared by a mixture of silicone oil, RTV141A polymer, and 30% of iron particles of total mixture, the mixture obtained is mixed for about 15 minutes to obtain an elastomer paste with good homogenization. In order to develop a magnetorheological elastomer (MRE), this paste is injected into an aluminum mold and subjected to a magnetic field. In our work, we have chosen an ideal percentage of filling of 30%, to obtain the best characteristics of the MRE. The mechanical characteristics obtained by dynamic mechanical viscoanalyzer (DMA) are used in the two numerical approaches. The natural frequencies and the modal damping of the sandwich plate are calculated and discussed for various magnetic field intensities. The results obtained by the two methods are compared. These off‐axis anisotropic MRE structures could open up new opportunities in various fields of aeronautics, aerospace, mechanical engineering and civil engineering. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20smart%20sandwich%20plate" title="hybrid smart sandwich plate">hybrid smart sandwich plate</a>, <a href="https://publications.waset.org/abstracts/search?q=vibratory%20behavior" title=" vibratory behavior"> vibratory behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=FEM" title=" FEM"> FEM</a>, <a href="https://publications.waset.org/abstracts/search?q=Ritz%20approach" title=" Ritz approach"> Ritz approach</a>, <a href="https://publications.waset.org/abstracts/search?q=MRE" title=" MRE"> MRE</a> </p> <a href="https://publications.waset.org/abstracts/177269/modeling-and-simulation-of-vibratory-behavior-of-hybrid-smart-composite-plate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177269.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">68</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4051</span> Vibration Frequency Analysis of Sandwich Nano-Plate on Visco Pasternak Foundation by Using Modified Couple Stress Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Khani%20Arani">Hamed Khani Arani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Shariyat"> Mohammad Shariyat</a>, <a href="https://publications.waset.org/abstracts/search?q=Armaghan%20Mohammadian"> Armaghan Mohammadian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, the free vibration of a rectangular sandwich nano-plate (SNP) made of three smart layers in the visco Pasternak foundation is studied. The core of the sandwich is a piezo magnetic nano-plate integrated with two layers of piezoelectric materials. First-order shear deformation plate theory is utilized to derive the motion equations by using Hamilton’s principle, piezoelectricity, and modified couple stress theory. Elastic medium is modeled by visco Pasternak foundation, where the damping coefficient effect is investigated on the stability of sandwich nano-plate. These equations are solved by the differential quadrature method (DQM), considering different boundary conditions. Results indicate the effect of various parameters such as aspect ratio, thickness ratio, shear correction factor, damping coefficient, and boundary conditions on the dimensionless frequency of sandwich nano-plate. The results are also compared by those available in the literature, and these findings can be used for automotive industry, communications equipment, active noise, stability, and vibration cancellation systems and utilized for designing the magnetostrictive actuator, motor, transducer and sensors in nano and micro smart structures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=free%20vibration" title="free vibration">free vibration</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20couple%20stress%20theory" title=" modified couple stress theory"> modified couple stress theory</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20nano-plate" title=" sandwich nano-plate"> sandwich nano-plate</a>, <a href="https://publications.waset.org/abstracts/search?q=visco%20Pasternak%20foundation" title=" visco Pasternak foundation"> visco Pasternak foundation</a> </p> <a href="https://publications.waset.org/abstracts/125478/vibration-frequency-analysis-of-sandwich-nano-plate-on-visco-pasternak-foundation-by-using-modified-couple-stress-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125478.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">139</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4050</span> Hexagonal Honeycomb Sandwich Plate Optimization Using Gravitational Search Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Boudjemai">A.

Hence, this work deals with the presentation of an optimal design of hexagonal honeycomb sandwich structures subjected to space environment.

One or both faces may be flat, lightly profiled or fully profiled. Until recently sandwich panel construction in Egypt has been widely used in cold-storage buildings, cold trucks, prefabricated buildings and insulation in construction. Recently new techniques are used in mass production of Sandwich Materials such as Reaction Injection Molding (RIM) and Vacuum bagging technique. However, in recent times their use has increased significantly due to their widespread structural applications in building systems. Structural sandwich panels generally used in Egypt comprise polyurethane foam core and thinner (0.42 mm) and high strength about 550 MPa (yield strength) flat steel faces bonded together using separate adhesives and By RIM technique. In this paper, we will use a new technique in sandwich panel preparation by using different face sheet materials in combination with polyurethane foam to form sandwich panel structures. Previously, PU Foam core with same thin 2 faces material was used, but in this work, we use different face materials and thicknesses for the upper face sheet such as Galvanized steel sheets (G.S),Aluminum sheets (Al),Fiberglass sheets (F.G) and Aluminum-Rubber composite sheets (Al/R) with polyurethane foam core 10 mm thickness and 45 Kg/m3 Density and Galvanized steel as lower face sheet. Using Aluminum-Rubber composite sheets as face sheet is considered a hybrid composite sandwich panel which is built by Hand-Layup technique by using PU glue as adhesive. This modification increases the benefits of the face sheet that will withstand different working environments with relatively small increase in its weight and will be useful in several applications. In this work, a 3-point bending test is used assistant professor to measure the most important factor in sandwich materials that is strength to weight ratio(STW) for different combinations of sandwich structures and make a comparison to study the effect of changing the face sheet material on the mechanical behavior of PU sandwich material. Also, the density of the different prepared sandwich materials will be measured to obtain the specific bending strength. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20sandwich%20panel" title="hybrid sandwich panel">hybrid sandwich panel</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20behavior" title=" mechanical behavior"> mechanical behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=PU%20foam" title=" PU foam"> PU foam</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20panel" title=" sandwich panel"> sandwich panel</a>, <a href="https://publications.waset.org/abstracts/search?q=3-point%20bending" title=" 3-point bending"> 3-point bending</a>, <a href="https://publications.waset.org/abstracts/search?q=flexural%20strength" title=" flexural strength"> flexural strength</a> </p> <a href="https://publications.waset.org/abstracts/47190/effect-of-upper-face-sheet-material-on-flexural-strength-of-polyurethane-foam-hybrid-sandwich-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47190.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4047</span> Flexural Test of Diversing Foam Core Sandwich Composites </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Santhana%20Krishnan%20R">Santhana Krishnan R</a>, <a href="https://publications.waset.org/abstracts/search?q=Preetha%20C"> Preetha C</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sandwich construction with strong and stiffness facing and light weight cores is increasingly cores being used in structures where the predominant loads are flexural.

This paper is the continuation of our previous work, in which we proposed the usage of Foglets and VLC link between smart vehicles and road side assets. In this paper, we propose a hybrid communication system for asset management and emergency reporting architecture for smart transportation. We incorporate Foglets along with visible light communication (VLC) and radio frequency (RF) communication. We present the channel model and parameters of a hybrid model to support an intelligent transportation system (ITS) system. Simulations show high improvement in the system performance in terms of communication range and received data. We present a comparative analysis of a hybrid ITS system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Internet%20of%20Things" title="Internet of Things">Internet of Things</a>, <a href="https://publications.waset.org/abstracts/search?q=Foglets" title=" Foglets"> Foglets</a>, <a href="https://publications.waset.org/abstracts/search?q=VLC" title=" VLC"> VLC</a>, <a href="https://publications.waset.org/abstracts/search?q=RF" title=" RF"> RF</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20vehicle" title=" smart vehicle"> smart vehicle</a>, <a href="https://publications.waset.org/abstracts/search?q=roadside%20asset%20management" title=" roadside asset management"> roadside asset management</a> </p> <a href="https://publications.waset.org/abstracts/158829/performance-analysis-of-a-hybrid-channel-for-foglet-assisted-smart-asset-reporting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158829.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4044</span> Vibration Analysis of FGM Sandwich Panel with Cut-Outs Using Refined Higher-Order Shear Deformation Theory (HSDT) Based on Isogeometric Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lokanath%20Barik">Lokanath Barik</a>, <a href="https://publications.waset.org/abstracts/search?q=Abinash%20Kumar%20Swain"> Abinash Kumar Swain</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents vibration analysis of FGM sandwich structure with a complex profile governed by refined higher-order shear deformation theory (RHSDT) using isogeometric analysis (IGA). Functionally graded sandwich plates provide a wide range of applications in aerospace, defence, and aircraft industries due to their ability to distribute material functions to influence the thermo-mechanical properties as desired. In practical applications, these structures generally have intrinsic profiles, and their response to loads is significantly affected due to cut-outs. IGA is primarily a NURBS-based technique that is effective in solving higher-order differential equations due to its inherent C1 continuity imposition in solution space for a single patch. Complex structures generally require multiple patches to accurately represent the geometry, and hence, there is a loss of continuity at adjoining patch junctions. Therefore, patch coupling is desired to maintain continuity requirements throughout the domain. In this work, a novel strong coupling approach is provided that generates a well-defined NURBS-based model while achieving continuity. The methodology is validated by free vibration analysis of sandwich plates with present literature. The results are in good agreement with the analytical solution for different plate configurations and power law indexes. Numerical examples of rectangular and annular plates are discussed with variable boundary conditions. Additionally, parametric studies are provided by varying the aspect ratio, porosity ratio and their influence on the natural frequency of the plate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vibration%20analysis" title="vibration analysis">vibration analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=FGM%20sandwich%20structure" title=" FGM sandwich structure"> FGM sandwich structure</a>, <a href="https://publications.waset.org/abstracts/search?q=multipatch%20geometry" title=" multipatch geometry"> multipatch geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=patch%20coupling" title=" patch coupling"> patch coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=IGA" title=" IGA"> IGA</a> </p> <a href="https://publications.waset.org/abstracts/174829/vibration-analysis-of-fgm-sandwich-panel-with-cut-outs-using-refined-higher-order-shear-deformation-theory-hsdt-based-on-isogeometric-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174829.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">84</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4043</span> The Free Vibration Analysis of Honeycomb Sandwich Beam using 3D and Continuum Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCrkan%20%C5%9Eakar">Gürkan Şakar</a>, <a href="https://publications.waset.org/abstracts/search?q=Fevzi%20%C3%87akmak%20Bolat"> Fevzi Çakmak Bolat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study free vibration analysis of aluminum honeycomb sandwich structures were carried out experimentally and numerically.

So application of metallic joints between sandwich panels is increasing. Various joining methods are available such as mechanically fastened joints (riveting or bolting) or adhesively bonded joints and choosing one of them depends on the application. In this research, sandwich specimens were fabricated with two different types of metallic connections with dissimilar geometries. These specimens included beams and plates and were manufactured using glass-epoxy skins and aluminum honeycomb core. After construction of the specimens, bending and low velocity impact tests were executed on them and the behaviors of specimens were discussed. Numerical models were developed using LS-DYNA software and validated with test results. Finally, parametric studies were performed on the thicknesses and lengths of two connections by employing the numerical models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=connection" title="connection">connection</a>, <a href="https://publications.waset.org/abstracts/search?q=honeycomb" title=" honeycomb"> honeycomb</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20velocity%20impact" title=" low velocity impact"> low velocity impact</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20panel" title=" sandwich panel"> sandwich panel</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20test" title=" static test"> static test</a> </p> <a href="https://publications.waset.org/abstracts/179005/static-and-dynamic-behaviors-of-sandwich-structures-with-metallic-connections" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179005.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">58</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4041</span> Optimization of FGM Sandwich Beams Using Imperialist Competitive Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeed%20Kamarian">Saeed Kamarian</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Shakeri"> Mahmoud Shakeri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sandwich structures are used in a variety of engineering applications including aircraft, construction and transportation where strong, stiff and light structures are required.

A generalized power-law distribution with four parameters is considered for material distribution through the thicknesses of face layers. Since the search space is large, the optimization processes becomes so complicated and too much time consuming. Thus a novel meta–heuristic called Imperialist Competitive Algorithm (ICA) which is a socio-politically motivated global search strategy is implemented to improve the speed of optimization process.

Exposure to space radiation not only can affect the health of astronauts but also can disrupt or damage materials and electronics. Hazards to materials include degradation of properties, such as, modulus, strength, or glass transition temperature. Electronics may experience single event effects, gate rupture, burnout of field effect transistors and noise. Presently aluminum is the major component in most of the space structures due to its lightweight and good structural properties. However, aluminum is ineffective at blocking space radiation. Therefore, most of the past research involved studying at polymers which contain large amounts of hydrogen. Again, these materials are not structural materials and would require large amounts of material to achieve the structural properties needed. One of the materials to alleviate this problem is polymeric composite materials, which has good structural properties and use polymers that contained large amounts of hydrogen. This paper presents steps involved in fabrication of multi-functional hybrid sandwich panels that can provide beneficial radiation shielding as well as structural strength. Multifunctional hybrid sandwich panels were manufactured using vacuum assisted resin transfer molding process and were subjected to radiation treatment. Study indicates that various nanoparticles including Boron Nano powder, Boron Carbide and Gadolinium nanoparticles can be successfully used to block the space radiation without sacrificing the structural integrity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-functional" title="multi-functional">multi-functional</a>, <a href="https://publications.waset.org/abstracts/search?q=polymer%20composites" title=" polymer composites"> polymer composites</a>, <a href="https://publications.waset.org/abstracts/search?q=radiation%20shielding" title=" radiation shielding"> radiation shielding</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20composites" title=" sandwich composites"> sandwich composites</a> </p> <a href="https://publications.waset.org/abstracts/44771/fabrication-of-nanoengineered-radiation-shielding-multifunctional-polymeric-sandwich-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">286</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4039</span> Quasi-Static Resistance Function Quantification for Lightweight Sandwich Panels: Experimental Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasser%20A.%20Khalifa">Yasser A.

According to the American and Canadian codes for blast resistant designs of buildings UFC 3-340-02, ASCE/SEI 59-11, and CSA/ S850-12 the dynamic behavior is related to the static behavior under uniform loading. The target was to design a lightweight, relatively cheap, and quick sandwich panel to be employed as a sacrificial cladding for important buildings. For that an available corrugated cold formed steel sheet profile in North America was used as a core for the sandwich panel, in addition to using a quick, relatively low cost fabrication technique in the construction process. Six orthogonal corrugated core sandwich panels were tested and the influence of core sheet gauge on the behavior of the sandwich panels was explored using two different gauges. Failure modes, yield forces, ultimate forces, and corresponding deformations were determined and discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cold%20formed%20steel" title="cold formed steel">cold formed steel</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20structure" title=" lightweight structure"> lightweight structure</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20panel" title=" sandwich panel"> sandwich panel</a>, <a href="https://publications.waset.org/abstracts/search?q=sacrificial%20cladding" title=" sacrificial cladding"> sacrificial cladding</a>, <a href="https://publications.waset.org/abstracts/search?q=uniform%20loading" title=" uniform loading"> uniform loading</a> </p> <a href="https://publications.waset.org/abstracts/19165/quasi-static-resistance-function-quantification-for-lightweight-sandwich-panels-experimental-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19165.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">488</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4038</span> Characterization of Two Hybrid Welding Techniques on SA 516 Grade 70 Weldments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20T.%20Z.%20Butt">M.

Heat input is the major parameter during welding that may bring significant changes in the microstructure as well as the mechanical properties. Different welding technique has different heat input rate per unit surface area. Materials with large thickness are dealt with different combination of welding techniques to achieve required mechanical properties. In the present research two schemes: Scheme 1: SMAW (Shielded Metal Arc Welding) & GTAW (Gas Tungsten Arc Welding) and Scheme 2: SMAW & SAW (Submerged Arc Welding) of hybrid welding techniques have been studied. The purpose of these schemes was to study hybrid welding effect on the microstructure and mechanical properties of the weldment, heat affected zone and base metal area. It is significant to note that the thickness of base plate was 12 mm, also welding conditions and parameters were set according to ASME Section IX. It was observed that two different hybrid welding techniques performed on two different plates demonstrated that the mechanical properties of both schemes are more or less similar. It means that the heat input, welding techniques and varying welding operating conditions & temperatures did not make any detrimental effect on the mechanical properties. Hence, the hybrid welding techniques mentioned in the present study are favorable to implicate for the industry using the plate thickness around 12 mm thick. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grade%2070" title="grade 70">grade 70</a>, <a href="https://publications.waset.org/abstracts/search?q=GTAW" title=" GTAW"> GTAW</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20welding" title=" hybrid welding"> hybrid welding</a>, <a href="https://publications.waset.org/abstracts/search?q=SAW" title=" SAW"> SAW</a>, <a href="https://publications.waset.org/abstracts/search?q=SMAW" title=" SMAW"> SMAW</a> </p> <a href="https://publications.waset.org/abstracts/51031/characterization-of-two-hybrid-welding-techniques-on-sa-516-grade-70-weldments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51031.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">339</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4037</span> Flexural Response of Glass Fiber Reinforced Polymer Sandwich Panels with 3D Woven Honeycomb Core</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elif%20Kalkanli">Elif Kalkanli</a>, <a href="https://publications.waset.org/abstracts/search?q=Constantinos%20Soutis"> Constantinos Soutis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of textile preform in the advanced fields including aerospace, automotive and marine has exponentially grown in recent years. These preforms offer excellent advantages such as being lightweight and low-cost, and also, their suitability for creating different fiber architectures with different materials whilst improved mechanical properties in certain aspects. In this study, a novel honeycomb core is developed by a 3Dweaving process. The assembly of the layers is achieved thanks to innovative weaving design. Polyester yarn is selected for the 3D woven honeycomb core (3DWHC). The core is used to manufacture a sandwich panel with 2x2 twill glass fiber composite face sheets. These 3DWHC sandwich panels will be tested in three-point bending. The in-plane and out-of-plane (through-the-thickness) mechanical response of the core will be examined as a function of cell size in addition to the flexural response of the sandwich panel. The failure mechanisms of the core and the sandwich skins will be reported in addition to flexural strength and stiffness.

In this study, meshless local Petrov-Galerkin (MLPG) method is employed to obtain the functionally graded (FG) plate’s natural frequencies. Effects of two parameters including thickness to height ratio and volume fraction index on the natural frequencies and total mass of plate are studied by using the MLPG results. Then the first natural frequency of the plate, for different conditions where MLPG data are not available, is predicted by an artificial neural network (ANN) approach which is trained by back-error propagation (BEP) technique.

In this study, the foam core, laminated facings’ sandwich panel with internal triangular rib configuration is impacted by a spherical steel projectile at different angles using ABAQUS finite element package and damage mechanics is studied. Laminated ribs’ structure is sub-divided into three formations; all zeros, all 45 and optimized combination of zeros and 45 degrees. Impact velocity is varied from 250 m/s to 500 m/s with an increment of 50 m/s. The impact damage can significantly demolish the structural integrity and energy absorption due to fiber breakage, matrix cracking, and de-bonding. Macroscopic fracture study of the panel and core along with load-displacement responses and failure modes are the key parameters in the design of smart ballistic resistant structures. Ballistic impact characteristics of panels are studied on different speed, different inclination angles and its dependency on the base, and core materials, ribs formation, and cross-sectional spaces among them are determined. Impact momentum, penetration and kinetic energy absorption data and curves are compiled to predict the first and proximity impact in an effort to enhance the dynamic energy absorption. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20energy%20absorption" title="dynamic energy absorption">dynamic energy absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=proximity%20impact" title=" proximity impact"> proximity impact</a>, <a href="https://publications.waset.org/abstracts/search?q=sandwich%20panels" title=" sandwich panels"> sandwich panels</a>, <a href="https://publications.waset.org/abstracts/search?q=impact%20momentum" title=" impact momentum"> impact momentum</a> </p> <a href="https://publications.waset.org/abstracts/60138/damage-of-laminated-corrugated-sandwich-panels-under-inclined-impact-loading" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60138.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">389</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4033</span> Pedestrian Safe Bumper Design from Commingled Glass Fiber/Polypropylene Reinforced Sandwich Composites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Onal">L.

Sensors and stimulators are usually recognized as smart devices of our environment. Simultaneously, IOT security brings up new issues. Internet connection and possibility of interaction with smart devices cause those devices to involve more in human life. Therefore, safety is a fundamental requirement in designing IOT. IOT has three remarkable features: overall perception, reliable transmission, and intelligent processing. Because of IOT span, security of conveying data is an essential factor for system security. Hybrid encryption technique is a new model that can be used in IOT. This type of encryption generates strong security and low computation. In this paper, we have proposed a hybrid encryption algorithm which has been conducted in order to reduce safety risks and enhancing encryption's speed and less computational complexity. The purpose of this hybrid algorithm is information integrity, confidentiality, non-repudiation in data exchange for IOT. Eventually, the suggested encryption algorithm has been simulated by MATLAB software, and its speed and safety efficiency were evaluated in comparison with conventional encryption algorithm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=internet%20of%20things" title="internet of things">internet of things</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20algorithm" title=" hybrid algorithm"> hybrid algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=privacy" title=" privacy"> privacy</a> </p> <a href="https://publications.waset.org/abstracts/69919/improving-the-security-of-internet-of-things-using-encryption-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69919.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4031</span> Free Vibration Analysis of Symmetric Sandwich Beams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibnorachid%20Zakaria">Ibnorachid Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Bikri%20Khalid"> El Bikri Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Benamar%20Rhali"> Benamar Rhali</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Abdoun"> Farah Abdoun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present work is to study the linear free symmetric vibration of three-layer sandwich beam using the energy method.

The diffraction intensity was measured by the diffractive optics technology or dotLab™ system. Two methods were evaluated in this study: direct immunoassay and direct sandwich immunoassay. In the direct immunoassay, human ferritin was captured by human ferritin antibodies immobilized on an avidin-coated sensor while the direct sandwich immunoassay had an additional step for the binding of a detector human ferritin antibody on the analyte complex. Both methods were repeatable with coefficient of variation values below 15%. The direct sandwich immunoassay had a linear response from 10 to 500 ng/mL which is wider than the 100-500 ng/mL of the direct immunoassay. The direct sandwich immunoassay also has a higher calibration sensitivity with value 0.002 Diffractive Intensity (ng mL-1)-1) compared to the 0.004 Diffractive Intensity (ng mL-1)-1 of the direct immunoassay. The limit of detection and limit of quantification values of the direct immunoassay were found to be 29 ng/mL and 98 ng/mL, respectively, while the direct sandwich immunoassay has a limit of detection (LOD) of 2.5 ng/mL and a limit of quantification (LOQ) of 8.2 ng/mL. In terms of accuracy, the direct immunoassay had a percent recovery of 88.8-93.0% in PBS while the direct sandwich immunoassay had 94.1 to 97.2%. Based on the results, the direct sandwich immunoassay is a better diffraction-based immunoassay in terms of accuracy, LOD, LOQ, linear range, and sensitivity. The direct sandwich immunoassay was utilized in the determination of human ferritin in blood serum and the results are validated by Chemiluminescent Magnetic Immunoassay (CMIA). The calculated Pearson correlation coefficient was 0.995 and the p-values of the paired-sample t-test were less than 0.5 which show that the results of the direct sandwich immunoassay was comparable to that of CMIA and could be utilized as an alternative analytical method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosensor" title="biosensor">biosensor</a>, <a href="https://publications.waset.org/abstracts/search?q=diffraction" title=" diffraction"> diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=ferritin" title=" ferritin"> ferritin</a>, <a href="https://publications.waset.org/abstracts/search?q=immunoassay" title=" immunoassay"> immunoassay</a> </p> <a href="https://publications.waset.org/abstracts/62082/development-of-a-direct-immunoassay-for-human-ferritin-using-diffraction-based-sensing-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62082.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">354</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4029</span> Geometrically Linear Symmetric Free Vibration Analysis of Sandwich Beam </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibnorachid%20Zakaria">Ibnorachid Zakaria</a>, <a href="https://publications.waset.org/abstracts/search?q=El%20Bikri%20Khalid"> El Bikri Khalid</a>, <a href="https://publications.waset.org/abstracts/search?q=Benamar%20Rhali"> Benamar Rhali</a>, <a href="https://publications.waset.org/abstracts/search?q=Farah%20Abdoun"> Farah Abdoun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present work is to study the linear free symmetric vibration of three-layer sandwich beam using the energy method.

The smart grid concept brings the idea that the power comes from various sources (continuous or intermittent), in various forms (AC or DC, high, medium or low voltage, etc.), and it must be integrated into the electric power system in a smart way to guarantee a continuous and reliable supply that complies with power quality and energy efficiency standards and grid code requirements. This idea brings questions for the different players like how the required power will be generated, what kind of power will be more suitable, how to store exceeding levels for short or long-term usage, and how to combine and distribute all the different generation power sources in an efficient way. To address these issues, there has been lots of development in recent years on the field of on-grid and off-grid hybrid power systems (HPS). These systems usually combine one or more modes of electricity generation together with energy storage to ensure optimal supply reliability and high level of energy security. Hybrid power systems combine power generation and energy storage technologies together with real-time energy management and innovative power quality and energy efficiency improvement functionalities. These systems help customers achieve targets for clean energy generation, they add flexibility to the electrical grid, and they optimize the installation by improving its power quality and energy efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microgrids" title="microgrids">microgrids</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20power%20systems" title=" hybrid power systems"> hybrid power systems</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage" title=" energy storage"> energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20quality%20improvement" title=" power quality improvement"> power quality improvement</a> </p> <a href="https://publications.waset.org/abstracts/127220/energy-efficient-microgrid-design-with-hybrid-power-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127220.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">145</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4027</span> Geometric Nonlinear Dynamic Analysis of Cylindrical Composite Sandwich Shells Subjected to Underwater Blast Load</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20Taskin">Mustafa Taskin</a>, <a href="https://publications.waset.org/abstracts/search?q=Ozgur%20Demir"> Ozgur Demir</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Mert%20Serveren"> M.

Considering that ship and submarine structures are mostly curved surfaces, it is extremely important and interesting to examine the destructive effects of underwater explosions on curvilinear surfaces. In this study, geometric nonlinear dynamic analysis of cylindrical composite sandwich shells subjected to instantaneous pressure load is performed. The instantaneous pressure load is defined as an underwater explosion and the effects of the liquid medium are taken into account. There are equations in the literature for pressure due to underwater explosions, but these equations have been obtained for flat plates. For this reason, the instantaneous pressure load equations are arranged to be suitable for curvilinear structures before proceeding with the analyses. Fluid-solid interaction is defined by using Taylor's Plate Theory. The lower and upper layers of the cylindrical composite sandwich shell are modeled as composite laminate and the middle layer consists of soft core. The geometric nonlinear dynamic equations of the shell are obtained by Hamilton's principle, taken into account the von Kàrmàn theory of large displacements. Then, time dependent geometric nonlinear equations of motion are solved with the help of generalized differential quadrature method (GDQM) and dynamic behavior of cylindrical composite sandwich shells exposed to underwater explosion is investigated. An algorithm that can work parametrically for the solution has been developed within the scope of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cylindrical%20composite%20sandwich%20shells" title="cylindrical composite sandwich shells">cylindrical composite sandwich shells</a>, <a href="https://publications.waset.org/abstracts/search?q=generalized%20differential%20quadrature%20method" title=" generalized differential quadrature method"> generalized differential quadrature method</a>, <a href="https://publications.waset.org/abstracts/search?q=geometric%20nonlinear%20dynamic%20analysis" title=" geometric nonlinear dynamic analysis"> geometric nonlinear dynamic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=underwater%20explosion" title=" underwater explosion"> underwater explosion</a> </p> <a href="https://publications.waset.org/abstracts/139669/geometric-nonlinear-dynamic-analysis-of-cylindrical-composite-sandwich-shells-subjected-to-underwater-blast-load" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139669.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">195</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4026</span> A Case Study on Smart Energy City of the UK: Based on Business Model Innovation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Minzheong%20Song">Minzheong Song </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this paper is to see a case of smart energy evolution of the UK along with government projects and smart city project like 'Smart London Plan (SLP)' in 2013 with the logic of business model innovation (BMI).

Nevertheless, traditional product development and production processes (molding, extrusion) are already reaching their limits or fail to address these trends of a flexible and digitized production in view of a product variability up to lot size one. Thus, upcoming innovative production concepts like the additive manufacturing technology basically create new opportunities with regard to extensive potentials in product development (constructive optimization) and manufacturing (economic individualization), but mostly suffer from insufficient strength regarding structural components. Therefore, this contribution presents an innovative technological and procedural conception of a hybrid additive manufacturing process (fiber-reinforced sandwich structures based on selective laser sintering technology) to overcome these current structural weaknesses, and consequently support the design of complex lightweight components. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=fiber-reinforced%20plastics%20%28FRP%29" title=" fiber-reinforced plastics (FRP)"> fiber-reinforced plastics (FRP)</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20design" title=" hybrid design"> hybrid design</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20design" title=" lightweight design"> lightweight design</a> </p> <a href="https://publications.waset.org/abstracts/63609/fiber-reinforced-sandwich-structures-based-on-selective-laser-sintering-a-technological-view" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/63609.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">297</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4024</span> Sandwich Structure Composites: Effect of Kenaf on Mechanical Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maizatulnisa%20Othman">Maizatulnisa Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Bukhari"> Mohamad Bukhari</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahurin%20Halim"> Zahurin Halim</a>, <a href="https://publications.waset.org/abstracts/search?q=Souad%20A.%20Muhammad"> Souad A.

Interface bonding between core and skin was controlled by varying kenaf content. Five different weight percentage of kenaf loading ranging from 10 wt% to 50 wt% were employed in the core manufacturing in order to study the mechanical properties of the sandwich composite. Properties of skin aluminium with epoxy were found to be affected by drying time of the adhesive. Mechanical behavior of manufactured sandwich composites in relation with properties of constituent materials was studied. It was found that 30 wt% of kenaf loading contributed to increase the flexural strength and flexural modulus up to 102 MPa and 32 Gpa, respectively. Analysis were done on the flatwise and edgewise compression test. For flatwise test, it was found that 30 wt% of fiber loading could withstand maximum force until 250 kN, with compressive strength results at 96.94 MPa. However, at edgewise compression test, the sandwich composite with same fiber loading only can withstand 31 kN of the maximum load with 62 MPa of compressive strength results. <p
