<div id="abstractTextBlock587061" class="volume-info volume-info-text volume-info-description"> Abstract: The dynamic vulcanization technique is a process of crosslinking an elastomer during mixing with a molten state thermoplastic, resulting in a new class of thermoplastic elastomers (TPEs): vulcanized thermoplastics (TPVs). This technique obtains materials with rubber behavior at room temperature, but processed as plastics at high temperatures, especially by extrusion and injection. The advantage of using the process of obtaining thermoplastic elastomers is that traditional elastomers require several steps in their processing. From an environmental point of view, vulcanized thermoplastics are interesting, since these materials keep their properties practically unchanged with direct recycling, without the need for any treatments. The objective of this work was to develop a new system of reactive compatibilization for the PP/NBR mixture, by means of the click chemistry technique by the reaction of the thiol-ene type, using as a compatibilizing agent the addition of EVASH (Poli (ethylene-co-alcoholicvinyl)-co-mercapto-vinyl acetate), resulting from the chemical modification of EVA (poly (acrylonitrile-co-butadiene)) with mercaptan groups by transesterification. The ionic liquid acted as a catalyst, optimizing the transesterification reaction of EVA, to obtain EVASH with a greater presence of -SH to EVA, obtaining more rigid systems due to the click thiol-ene bond. </div> <div> <a data-readmore="{ block: '#abstractTextBlock587061', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 1 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.909.11">Peridynamic Model for Tensile Elongation and Fracture Simulations of Polymethyl Methacrylate Notched Specimens</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Muhammad Azim Azizi, Mohd Faiz Mohd Ridhuan, Mohd Zakiyuddin Mohd Zahari, Sharafiz Abdul Rahim, Muhammad Amin Azman </div> </div> <div id="abstractTextBlock587967" class="volume-info volume-info-text volume-info-description"> Abstract: This paper presents the peridynamic (PD) numerical model for simulating a tensile test until total fracture for a brittle polymeric material namely polymethyl methacrylate (PMMA). U-notched and V-notched specimens were used to investigate the effect of the notches on the elongation and fracture of PMMA. The tensile elongation of PMMA exhibits nonlinearity with respect to the applied load, while the fracture occurs when the material stress has reached the ultimate tensile stress of the material. Similar elongation and fracture properties were applied on PD simulations. Two types of elongation equation are used namely brittle and ductile equations to form PD-brittle and PD-ductile models. The published experimental data of tensile fracture test on notched PMMA specimens are used as reference to validate the simulations of the PD models. The PD numerical force-extension curves have good quantitative similarity for V-notched specimen but adequate quantitative similarity for U-notched specimen. As for the quality of the fractured specimen shape, the PD simulations have good similarity for the V-notched specimen but adequate similarity for the U-notched specimen. The plot of the internal force distribution from the simulations of PD shows good qualitative similarity to the plot of the stress distribution from the published data of FEM in terms of stress concentration. From the PD results, it is observed that the PD-ductile model has better capability in producing accurate simulation of the notched specimens than the PD-brittle model. </div> <div> <a data-readmore="{ block: '#abstractTextBlock587967', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 11 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.909.29">Thermo-Mechanical Bending for Hybrid Material Plates Perfect-Imperfect Rectangular Using High Order Theory</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Zerrouki Otmane, Merdaci Slimane, Hadj Mostefa Adda </div> </div> <div id="abstractTextBlock589616" class="volume-info volume-info-text volume-info-description"> Abstract: In this paper, a higher order shear deformation theory is used to analyse the thermo-mechanical bending response of perfect-imperfect rectangular plates for hybrid ceramic and metal type (FGP) functionally graded plates with porosities. Based on the mixing law, the FG porous material qualities fluctuate with the thickness of the FGP layer. The equilibrium equations are found using the total potential energy approach. For simply supported (FGP) porous plates, the thermo-mechanical response is calculated. Analytical research shows the correctness of the existing high-order shear deformation theory in predicting the thermo-mechanical response of perfect-imperfect rectangular FG plates. Geometric characteristics, thickness ratios, gradient indices, porosity coefficients, mechanical loading, and thermal loading are all covered. According to the findings, the proposed hypothesis is more likely to be correct when it comes to the thermo-mechanical response of FG porous plates. </div> <div> <a data-readmore="{ block: '#abstractTextBlock589616', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 29 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.909.45">Numerical and Experimental Analysis of Segmented Porous Implant Fabricated by 3D Printing and CNC Composite Machining Technology</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Xiao Zhang, Jin Yang Zhang, Jian Yu Chen, Xian Shuai Chen </div> </div> <div id="abstractTextBlock589572" class="volume-info volume-info-text volume-info-description"> Abstract: The purpose of this study was to design porous implants with particular structure and evaluate their biomechanical behavior. Thus, a segmented porous dental implant (SPDI) was designed and manufactured by 3D Printing and computer numerical control (CNC) composite machining technology. The FE analysis was used to investigate its static mechanical property. Fatigue test was performed to verify its fatigue life. Resonance frequency analysis and pull-out tests were carried out to study its primary stability. Results indicated that better stress distribution was observed for SPDI. Fatigue test showed that no fracture or failure occurred in SPDI samples after 8 million cycles. The average implant stability quotient (ISQ) values of the SPDI inserted into the porous and denser artificial bones were 68.7 and 73.0 respectively. The average maximum pull-out force of SPDI extracted from the artificial bones was 347.5 N. This study provided a new structural design and manufacturing method for porous implant.

According to the test results, the nonlinear regression analysis was conducted and further a prediction method of shear capacity was proposed for CFRP grid-strengthened RC beams. The results showed that the shear behavior of strengthened beams were obviously improved, mainly due to CFRP grid. The shear strengthening effects of CFRP grid not only had a relation to the intervals of grids, but also were closely related to the shear span ratios and the concrete strengths, and thus both of them also cannot be ignored in design. The novel prediction method proposed in this paper, was verified by collecting data and regarded as a good predictor. </div> <div> <a data-readmore="{ block: '#abstractTextBlock589914', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 55 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.909.63">Research on Comprehensive Technology of Steel Grid Installation and Integral Jacking</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Zheng Ji Li, Chun Hui Wang, Qiu Shi Han, Zhen Zhen Quan, Hai Xuan Zhang </div> </div> <div id="abstractTextBlock590469" class="volume-info volume-info-text volume-info-description"> Abstract: In this paper, through the construction simulation of the installation and jacking of a large steel grid project, ANSYS software is used to select the corresponding finite element module, and by analyzing the construction models of different modes and different load conditions, the analysis results and structural models are displayed.

Numerous non-destructive testing (NDT) techniques have been adapted to inspect aircraft structures and are currently used according to appropriate protocols. However, many of them provide only qualitative results, such as the D-Sight optical NDT technique used for inspections in aviation. In this study, a concept of improvement of the D-Sight technique is proposed by means of appropriate experimental program and processing procedures applied to the resulting images from inspection.

However, the products must also maintain high quality and reliability. An efficient inspection technique should be conducted for the improvement in the manufacturing quality. In order to achieve high inspection rate, optical inspection based on machine vision often raises the threshold of the judgment and this will worsen false detection. In this study, we propose a high-accuracy optical inspection system based on deep learning technology. Various defects in screw head are precisely detected and analyzed, which include surface damage, unprocessed, and stripped surfaces. An industrial camera and microscope system are employed to collect the raw images of metal screws with different defect types. The raw images of 3200 are utilized to train the designed convolutional neural networks. The experimental results indicate that the proposed system reaches a detection accuracy of 92.8% and the average detection speed is 0.03 second per image. In comparison with conventional machine vision methods, the proposed measurement system is more suitable for the inspection of industrial production line. </div> <div> <a data-readmore="{ block: '#abstractTextBlock590495', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 75 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.909.81">Magnetic Structured Triboelectric Nanogenerators for Energy Harvesting</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Ali Matin Nazar, King James Egbe, Peng Cheng Jiao </div> </div> <div id="abstractTextBlock589609" class="volume-info volume-info-text volume-info-description"> Abstract: Abstract. Triboelectric nanogenerators (TENG) have made significant progress as a sustainable energy harvesting technique due to their ease of assembly, high power density, good stability and cost-efficiency. This study develops the magnetic structured triboelectric nanogenerators (MS-TENG) for energy harvesting with different loading frequency. The MS-TENG use magnetic force in the sliding mode to provide the repulsive force. The dielectric and electrode components, in particular, are appropriately connected to the circuit, which is attached to the digital oscilloscope for voltage performance. The copper capsules in mode two were the most effective design for the MS-TENG. The highest load-circuit voltage of 4.0 V is obtained for the copper (Cu) MS-TENG in mode 2 (dielectric capsule designed in mode 2 is first coated with a layer of Cu or Al and then covered with Kapton). A peak power in this design is 3.4 碌W. The suggested MS-TENG offers a practical way to gather electrical energy via the triboelectric effect, which are suitable for multifunctional applications. </div> <div> <a data-readmore="{ block: '#abstractTextBlock589609', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 81 </div> </div> <div class="block-bottom-pagination"> <div class="pager-info"> <p>Showing 1 to 10 of 12 Paper Titles</p> </div> <div class="pagination-container"><ul class="pagination"><li class="active"><span>1</span></li><li><a href="/AMM.909/2">2</a></li><li class="PagedList-skipToNext"><a href="/AMM.909/2" rel="next">></a></li></ul></div> </div> </div> </div> </div> </div> </div> </div> <div class="social-icon-popup"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-popup-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-popup-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-popup-icon social-icon"></i></a> </div> </div> <div class="sc-footer"> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="footer-menu col-md-12 col-sm-12 col-xs-12"> <ul class="list-inline menu-font"> <li><a href="/ForLibraries">For Libraries</a></li> <li><a href="/ForPublication/Paper">For Publication</a></li> <li><a href="/insights" target="_blank">Insights</a></li> <li><a href="/DocuCenter">Downloads</a></li> <li><a href="/Home/AboutUs">About Us</a></li> <li><a href="/PolicyAndEthics/PublishingPolicies">Policy & Ethics</a></li> <li><a href="/Home/Contacts">Contact Us</a></li> <li><a href="/Home/Imprint">Imprint</a></li> <li><a href="/Home/PrivacyPolicy">Privacy Policy</a></li> <li><a href="/Home/Sitemap">Sitemap</a></li> <li><a href="/Conferences">All Conferences</a></li> <li><a href="/special-issues">All Special Issues</a></li> <li><a href="/news/all">All News</a></li> <li><a href="/read-and-publish-agreements">Read & Publish Agreements</a></li> </ul> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12"> <a href="https://www.facebook.com/Scientific.Net.Ltd/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon facebook-footer-icon social-icon"></i></a> <a href="https://twitter.com/Scientific_Net/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon twitter-footer-icon social-icon"></i></a> <a href="https://www.linkedin.com/company/scientificnet/" target="_blank" rel="noopener" title="Scientific.Net"><i class="inline-icon linkedin-footer-icon social-icon"></i></a> </div> </div> </div> </div> <div class="line-footer"></div> <div class="footer-fluid"> <div class="container"> <div class="row"> <div class="col-xs-12 footer-copyright"> <p> © 2024 Trans Tech Publications Ltd.
