Research ArticleOpen accessPhrase in the titleA Simplified Two-Dimentional Unit Cell Model for Analyzing the Transverse Shear Stiffness of Three-Dimentional Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a complex three-dimensional model affects the speed of calculation time. A simplified two-dimensional model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents a study on the analysis of the transverse shear stiffness of three-dimensional truss-like core sandwich beam using a simplified two-dimensional unit … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 7,176 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Reduced Finite Element Model for Analyzing the Transverse Shear Stiffness of Truss-Like Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In structural analysis using finite element software, a number of finite element equations affect the speed of calculation time. A reduced finite element model should be used for analyzing structural responses to reduce the calculation time. Approach: This study presents the analysis of transverse shear stiffness of truss-like core sandwich beam using the reduced finite element model based … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,589 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleFinite Element Study of the Stress Response of Bi-Directional Corrugated-Strip Core Sandwich BeamSuphattharachai Chomphan, Manit LeekitwattanaProblem statement: In engineering design, stress affects the size of structural member. A suitable topology of structure should be designed to optimize the stress. Approach: This study presents an alternative topology of truss-like core sandwich beam referred to here as bi-directional corrugated-strip core topology. A finite element method is used to study the stress response of three point loaded truss-like … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 7,060 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleComputational Investigation of Elastoplastic Deformation of a Sandwich Beam on the Elastic FoundationMoh’d Ishaq Abu HalawaElastoplastic bending of a sandwich beam with a rigid compressible filler on an elastic base has been studied. To describe kinematics of asymmetrical across thickness pack in the bearing layers the Bernoulli hypotheses have been accepted. Displacements in the filler vary linearly over thickness. The distributed superficial loading simulates the hydrostatic effect of the ambient liquid. The reaction of the … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,567 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPhysical Nonlinearity Under Cyclic Loading In Neutron FlowAtwa D. Zeyad, E.I. StarovoitovThe influence of neutron irradiation on the nonlinear elastoplastic deformation of the constructions components under cyclic force disturbance was investigated. The formula of irradiation reinforcement was suggested depending on the experimental data, and the theorem of variable loading was proved. The problem of metal-polymeric sandwich beam was solved numerically. …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,776 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of Multi-Layered Laminated Glass Beams in Lateral-Torsional BucklingGabriel Neves Alves FerreiraThis article proposes a methodology for the structural design of multi-layered glass beams considering lateral-torsional buckling. The basis is the use of two separate effective thicknesses to determine flexural and torsional rigidities, based respectively on the Enhanced Effective Thickness (EET) and sandwich theory. Analytical formulae are then used to calculate the elastic critical bending moment and a design curve is … …International Journal of Structural Glass and Advanced Materials Research, Vol. 6, Issue 1 · 25 Oct 2022 · 9,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Objective Evolutionary Optimization of Sandwich Structures: An Evaluation by Elitist Non-dominated Sorting Evolution StrategyIlyani Akmar, A.B, O. Kramer, T. RabczukIn this study, an application of evolutionary multi-objective optimization algorithms on the optimization of sandwich structures is presented. The solution strategy is known as Elitist Non-Dominated Sorting Evolution Strategy (ENSES) wherein Evolution Strategies (ES) as Evolutionary Algorithm (EA) in the elitist Non-dominated Sorting Genetic algorithm (NSGA-II) procedure. Evolutionary algorithm seems a compatible approach to resolve multi-objective optimization problems because it … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 7,323 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicroelectrical Mechanical Systems Switch for Designing Multi-Band AntennaA.H.M. Zahirul Alam, Md. Rafiqul Islam, Sheroz Khan, Muhammad Mahbubur RashidProblem statement: In this study Microelectrical Mechanical System (MEMS) switches were proposed to design a reconfigurable/multi-band antenna to replaced PIN diode switches or semiconductor switches due to lower insertion losses, good isolation, much lower intermodulation distortion, and lower power consumption. The antenna is able to operate at very high frequencies. Approach: A reconfigurable antenna that is capable to operate at … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 6,687 accessesView PDFCite
