The complete formulation of the implementation process using a fully implicit integration scheme, i.e., the classic backward Euler method, is presented, and relevant aspects of the yield criterion are introduced. In order to solve nonlinear differential and algebraic equations, the line-search algorithm was adopted in the user-defined material subroutine (UMAT) to expand the convergence domain of the iterative Newton-Raphson method. The developed subroutine was used to simulate a challenging computational problem with complex stress states, i.e., deep drawing of an anisotropic aluminum alloy AA3105. The accuracy and stability of the developed subroutine were confirmed by comparing the numerically predicted earing and thickness variation profiles with the experimental results, which showed an excellent agreement between numerical and experimental earing and thickness profiles. The integration of the BBC2003 yield criterion into ABAQUS/Standard represents a significant contribution to the field of computational mechanics and provides a useful tool for analyzing the mechanical behavior of anisotropic materials subjected to complex loading conditions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=BBC2003%20yield%20function" title="BBC2003 yield function">BBC2003 yield function</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20anisotropy" title=" plastic anisotropy"> plastic anisotropy</a>, <a href="https://publications.waset.org/abstracts/search?q=fully%20implicit%20integration%20scheme" title=" fully implicit integration scheme"> fully implicit integration scheme</a>, <a href="https://publications.waset.org/abstracts/search?q=line%20search%20algorithm" title=" line search algorithm"> line search algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=explicit%20and%20implicit%20integration%20schemes" title=" explicit and implicit integration schemes"> explicit and implicit integration schemes</a> </p> <a href="https://publications.waset.org/abstracts/166034/finite-element-analysis-for-earing-prediction-incorporating-the-bbc2003-material-model-with-fully-implicit-integration-method-derivation-and-numerical-algorithm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166034.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">75</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">457</span> An Integrated Mixed-Integer Programming Model to Address Concurrent Project Scheduling and Material Ordering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Babak%20H.%20Tabrizi">Babak H.

There are different advantages for introducing permanent magnets into the rotor flux barriers, some of which are to saturate the rotor iron ribs, to increase the motor torque density and to improve the power factor. Moreover, the d-axis and q-axis inductances are of great importance to simultaneously achieve maximum developed torque and low torque ripple. Therefore, sensitivity analysis of the rotor geometry of an 8-pole external-rotor permanent magnet assisted synchronous reluctance motor is performed. Several magnetically accurate finite element analyses (FEA) are conducted to characterize the electromagnetic performance of the motor. The analyses validate torque and power factor equations for the proposed external-rotor motor. Based upon the obtained results and due to an additional term, permanent magnet torque, added to the reluctance torque, the electromagnetic torque of the PMaSynRM increases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=permanent%20magnet%20assisted%20synchronous%20reluctance%20motor" title="permanent magnet assisted synchronous reluctance motor">permanent magnet assisted synchronous reluctance motor</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20barrier" title=" flux barrier"> flux barrier</a>, <a href="https://publications.waset.org/abstracts/search?q=flux%20carrier" title=" flux carrier"> flux carrier</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20torque" title=" electromagnetic torque"> electromagnetic torque</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20power%20factor" title=" and power factor"> and power factor</a> </p> <a href="https://publications.waset.org/abstracts/85367/sensitivity-analysis-of-external-rotor-permanent-magnet-assisted-synchronous-reluctance-motor" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85367.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">331</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">452</span> Effects of Organic Fertilizer and Azotobacter and Azospirillum Bacteria on Concentration and Composition of Essential Oil of Coriander (Coriandrum Sativum L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20T.%20Darzi">M.

The objective of this study is to verify the ability of the Modified Newmark Method to include geometric non-linearity in addition to non-linearity due to cracking, and also to show the advantage of the established method to reconsider an ignored minor parameter in mathematical modeling, such as the effect of the cracking by extra geometric bending moment Ny on cross-section properties. The purpose of this investigation is not to present some new results for the instability of reinforced or composite concrete columns. Therefore, no kinds of non-linearity involved in the problem are considered here. Only as mentioned, it is a part of the verification of the new established method to solve two kinds of non-linearity P- δ effect and cracking together simultaneously. However, the Modified Newmark Method can be used to solve non-linearity of materials and time-dependent behavior of concrete. However, since it is out of the scope of this article, it is not considered. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stability" title="stability">stability</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20newmark%20method" title=" modified newmark method"> modified newmark method</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforced" title=" reinforced"> reinforced</a> </p> <a href="https://publications.waset.org/abstracts/42634/stability-of-composite-struts-using-the-modified-newmark-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42634.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">334</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">443</span> Investigating Elastica and Post Buckling Behavior Columns Using the Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The purpose of this article is to analyze the finite displacement of Columns by applying the Modified Newmark Method. This research will be performed on Columns subjected to compressive axial load, therefore the non-linearity of the geometry is also considered. If the considered strut is perfect, the governing differential equation contains a branching point in the solution path. Investigation into the Elastica is a part of generalizing the developed method. It presents the ability of the Modified Newmark Method in treating non-linear differential equations Derived from elastic strut stability problems. These include not only an approximate polynomial solution for the Elastica problems, but can also recognize the branching point and the stable solution. However, this investigation deals with the post-buckling response of elastic and pin ended columns subjected to central or equally eccentric axial loads. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=columns" title="columns">columns</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20modeling" title=" structural modeling"> structural modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=structures%20%26%20structural%20stability" title=" structures & structural stability"> structures & structural stability</a>, <a href="https://publications.waset.org/abstracts/search?q=loads" title=" loads"> loads</a> </p> <a href="https://publications.waset.org/abstracts/42637/investigating-elastica-and-post-buckling-behavior-columns-using-the-modified-newmark-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42637.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">312</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">442</span> The Role of Brand Experience in Customer Satisfaction and Customer Loyalty in Ayandeh Bank Branches in Tehran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Reza%20Agha%20Seyed%20Hosseini">Seyed Reza Agha Seyed Hosseini</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Hamelin"> Nicolas Hamelin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many marketing executives are looking for a comprehensive plan for delivering quality services and products that will create a distinct and unforgettable long-term experience for customers in dealing with their brand.

Teachers’ beliefs about formative assessment as well as their assessment roles have remained unexplored. This paper reports on the research results of our survey which is conducted in 20014 to examine issues relating to formative assessment in the university ESL classroom settings. The paper portrays the findings of a qualitative study on the formative assessment role and beliefs of a group of teachers of English as a Foreign Language (EFL) in the departments of English Languages in Iraqi Kurdistan universities. Participants of the study are 25 Kurdish EFL teachers from different departments of English languages. Close-ended and open-ended questionnaire is used to collect teacher’s beliefs and perceptions about the importance of formative assessment to improve the process of teaching and learning English language. The result of the study shows that teachers do not play a significant role in the assessment process because of top-down managerial approaches and educational system. The results prove that the teachers’ assessment beliefs and their key role in assessment should not be neglected. Our research papers pursued the following questions: What is the nature of formative assessment in a second language classroom setting? Do the teacher’s assessment practices reflect what she thinks about formative assessment? What are the teachers’ perceptions regarding the benefits of formative assessment for teaching and learning English language at the university level? <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=formative%20assessment" title="formative assessment">formative assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=teachers%E2%80%99%20beliefs%20and%20perceptions" title=" teachers’ beliefs and perceptions"> teachers’ beliefs and perceptions</a>, <a href="https://publications.waset.org/abstracts/search?q=assessment" title=" assessment"> assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=education%20reform" title=" education reform"> education reform</a>, <a href="https://publications.waset.org/abstracts/search?q=ESL" title=" ESL"> ESL</a> </p> <a href="https://publications.waset.org/abstracts/25935/the-impact-of-teachers-beliefs-and-perceptions-about-formative-assessment-in-the-university-esl-class-assistant-lecturer-barzan-hadi-hama-karim-university-of-halabja" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25935.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">402</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">440</span> Analysis of Hotel Websites to Attract Tourists in Iran, Case Study: Yazd County</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leila%20Habibi">Leila Habibi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Hakimi"> Hadi Hakimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hadi%20Sadeghian"> Hadi Sadeghian</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Jafari%20Mehrabadi"> Maryam Jafari Mehrabadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the importance of information technology and web-based information in tourism is very obvious.

The discussion will be restricted to plane frameworks containing a constant cross-section for each element. In addition, it is assumed that the frames are prevented from out-of-plane deflection. This part of the investigation is performed to generalize the established method for the assemblage structures such as frameworks. As explained, the governing differential equations are non-linear and cannot be formulated easily due to unknown axial load of the struts in the frame. By the assumption of constant axial load, the governing equations are changed to linear ones in most methods. Since the modeling and the solutions of the non-linear form of the governing equations are cumbersome, the linear form of the equations would be used in the established method. However, according to the ability of the method to reconsider the minor omitted parameters in modeling during the solution procedure, the axial load in the elements at each stage of the iteration can be computed and applied in the next stage. Therefore, the ability of the method to present an accurate approach to the solutions of non-linear equations will be demonstrated again in this paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nonlinear" title="nonlinear">nonlinear</a>, <a href="https://publications.waset.org/abstracts/search?q=stability" title=" stability"> stability</a>, <a href="https://publications.waset.org/abstracts/search?q=buckling" title=" buckling"> buckling</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20%20newmark%20method" title=" modified newmark method"> modified newmark method</a> </p> <a href="https://publications.waset.org/abstracts/42635/second-order-analysis-of-frames-using-modified-newmark-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42635.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">425</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">436</span> Investigating the Effect of Industrial Wastewater Application on the Concentration of Nitrate and Phosphate in the Soil of the Land Space of Chaharmahal and Bakhtiari Sefid Dasht Steel Company</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Alireza%20Farrokhzad">Seyed Alireza Farrokhzad</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Alavi"> Seyed Amin Alavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ebrahim%20Panahpour"> Ebrahim Panahpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of industrial wastewater affects the properties of soil, including its chemical properties. This research was conducted randomly in order to investigate the effect of industrial wastewater application on the concentration of nitrate and phosphate in loamy soil in the land space of Chaharmahal and Bakhtiari Sefid Dasht Steel Company. Industrial wastewater was added in ten irrigation periods in the three months of summer 2022 and was used in a part of the land space of the factory. After finishing the irrigation process with wastewater, the soil nitrate and phosphate values were measured at the depths of 0-25, 25-50 and 50-100 cm. The results showed that adding sewage to the soil increased nitrate and phosphate. The increase of these ions in the soil became loamy. Also, the results showed that the amount of phosphate in the soil decreases with increasing depth, while the amount of nitrate in the soil increases with increasing depth, which is due to the high mobility of nitrate along the soil profile. Also, with the increase in the level of use of wastewater, the amount of nitrate accumulation in the lower layers of the soil increased. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=industrial%20wastewater" title="industrial wastewater">industrial wastewater</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20chemical%20properties" title=" soil chemical properties"> soil chemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=loamy%20texture" title=" loamy texture"> loamy texture</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20space" title=" land space"> land space</a> </p> <a href="https://publications.waset.org/abstracts/176378/investigating-the-effect-of-industrial-wastewater-application-on-the-concentration-of-nitrate-and-phosphate-in-the-soil-of-the-land-space-of-chaharmahal-and-bakhtiari-sefid-dasht-steel-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/176378.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">435</span> Improving Decision-Making in Multi-Project Environments within Organizational Information Systems Using Blockchain Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Hossein%20Iranmanesh">Seyed Hossein Iranmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Nouri"> Hassan Nouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Reza%20Iranmanesh"> Seyed Reza Iranmanesh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the dynamic and complex landscape of today’s business, organizations often face challenges in impactful decision-making across multi-project settings. To efficiently allocate resources, coordinate tasks, and optimize project outcomes, establishing robust decision-making processes is essential. Furthermore, the increasing importance of information systems and their integration within organizational workflows introduces an additional layer of complexity. This research proposes the use of blockchain technology as a suitable solution to enhance decision-making in multi-project environments, particularly within the realm of information systems. The conceptual framework in this study comprises four independent variables and one dependent variable. The identified independent variables for the targeted research include: Blockchain Layer in Integrated Systems, Quality of Generated Information ,User Satisfaction with Integrated Systems and Utilization of Integrated Systems. The project’s performance, considered as the dependent variable and moderated by organizational policies and procedures, reflects the impact of blockchain technology adoption on organizational effectiveness1. The results highlight the significant influence of blockchain implementation on organizational performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-project%20environments" title="multi-project environments">multi-project environments</a>, <a href="https://publications.waset.org/abstracts/search?q=decision%20support%20systems" title=" decision support systems"> decision support systems</a>, <a href="https://publications.waset.org/abstracts/search?q=information%20systems" title=" information systems"> information systems</a>, <a href="https://publications.waset.org/abstracts/search?q=blockchain%20technology" title=" blockchain technology"> blockchain technology</a>, <a href="https://publications.waset.org/abstracts/search?q=decentralized%20systems." title=" decentralized systems."> decentralized systems.</a> </p> <a href="https://publications.waset.org/abstracts/185327/improving-decision-making-in-multi-project-environments-within-organizational-information-systems-using-blockchain-technology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185327.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">434</span> Numerical Study of Partial Penetration of PVDs In Soft Clay Soils Treatment Along With Surcharge Preloading (Bangkok Airport Case Study)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Mehdi%20Pardsouie">Mohammad Mehdi Pardsouie</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Mokhberi"> Mehdi Mokhberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Mohammad%20Ali%20Zomorodian"> Seyed Mohammad Ali Zomorodian</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Alireza%20Nasehi"> Seyed Alireza Nasehi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the challenging parts of every project, including prefabricated vertical drains (PVDs), is the determination of the depth of installation and its configuration. In this paper, Geostudio 2018 was used for modeling and verification of the full-scale test embankments (TS1, TS2, and TS3), which were constructed to study the effectiveness of PVDs for accelerating the consolidation and dissipation of the excess pore-pressures resulting from fill placement at Bangkok airport. Different depths and scenarios were modeled and the results were compared and analyzed. Since the ultimate goal is attaining pre-determined settlement, the settlement curve under soil embankment was used for the investigation of the results. It was shown that nearly in all cases, the same results and efficiency might be obtained by partial depth installation of PVDs instead of complete full constant length installation. However, it should be mentioned that because of distinct soil characteristics of clay soils and layers properties of any project, further investigation of full-scale test embankments and modeling is needed prior to finalizing the ultimate design by competent geotechnical consultants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=partial%20penetration" title="partial penetration">partial penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=surcharge%20preloading" title=" surcharge preloading"> surcharge preloading</a>, <a href="https://publications.waset.org/abstracts/search?q=excess%20pore%20water%20pressure" title=" excess pore water pressure"> excess pore water pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=Bangkok%20test%20embankments" title=" Bangkok test embankments"> Bangkok test embankments</a> </p> <a href="https://publications.waset.org/abstracts/143189/numerical-study-of-partial-penetration-of-pvds-in-soft-clay-soils-treatment-along-with-surcharge-preloading-bangkok-airport-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143189.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">207</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">433</span> A Robust Optimization Model for the Single-Depot Capacitated Location-Routing Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolsalam%20Ghaderi">Abdolsalam Ghaderi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the single-depot capacitated location-routing problem under uncertainty is presented. The problem aims to find the optimal location of a single depot and the routing of vehicles to serve the customers when the parameters may change under different circumstances. This problem has many applications, especially in the area of supply chain management and distribution systems. To get closer to real-world situations, travel time of vehicles, the fixed cost of vehicles usage and customers’ demand are considered as a source of uncertainty. A combined approach including robust optimization and stochastic programming was presented to deal with the uncertainty in the problem at hand. For this purpose, a mixed integer programming model is developed and a heuristic algorithm based on Variable Neighborhood Search(VNS) is presented to solve the model. Finally, the computational results are presented and future research directions are discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=location-routing%20problem" title="location-routing problem">location-routing problem</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20optimization" title=" robust optimization"> robust optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20programming" title=" stochastic programming"> stochastic programming</a>, <a href="https://publications.waset.org/abstracts/search?q=variable%20neighborhood%20search" title=" variable neighborhood search"> variable neighborhood search</a> </p> <a href="https://publications.waset.org/abstracts/83797/a-robust-optimization-model-for-the-single-depot-capacitated-location-routing-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83797.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">269</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">432</span> Investigation of Flexural – Torsion Instability of Struts Using Modified Newmark Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Amin%20Vakili">Seyed Amin Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sadat%20Vakili"> Sahar Sadat Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Ehsan%20Vakili"> Seyed Ehsan Vakili</a>, <a href="https://publications.waset.org/abstracts/search?q=Nader%20Abdoli%20Yazdi"> Nader Abdoli Yazdi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Differential equations are of fundamental importance in engineering and applied mathematics, since many physical laws and relations appear mathematically in the form of such equations. The equilibrium state of structures consisting of one-dimensional elements can be described by an ordinary differential equation. The response of these kinds of structures under the loading, namely relationship between the displacement field and loading field, can be predicted by the solution of these differential equations and on satisfying the given boundary conditions. When the effect of change of geometry under loading is taken into account in modeling of equilibrium state, then these differential equations are partially integrable in quartered. They also exhibit instability characteristics when the structures are loaded compressively. The purpose of this paper is to represent the ability of the Modified Newmark Method in analyzing flexural-torsional instability of struts for both bifurcation and non-bifurcation structural systems. The results are shown to be very accurate with only a small number of iterations. The method is easily programmed, and has the advantages of simplicity and speeds of convergence and easily is extended to treat material and geometric nonlinearity including no prismatic members and linear and nonlinear spring restraints that would be encountered in frames. In this paper, these abilities of the method will be extended to the system of linear differential equations that govern strut flexural torsional stability. <p
