Optimal shapes are found for reduced beam section of a cantilever H-beam subjected to forced cyclic displacement at the free end. The beam is discretized to finite elements, and a commercial software package called ABAQUS is used for elastoplastic analysis. The numerical results are first compared with experimental results to verify the accuracy. The objective function to be maximized is the di...

Wind turbine blades are the key components that allow extraction of energy from wind; these often subjected to accidental impacts which usually occurs on moving with maintenance tools, hail, or flying birds, resulting in a significant degradation structural integrity blade. In this paper, numerical simulation is adopted using finite element method (FEM) ABAQUS software investigate mechanical be...

This theoretical study describes the optical multilayer structure models leading to investigate Surface Plasmon Polariton (SPP) to an extern applied magnetic field at visible wavelenght using a 3D-FEM based on Comsol Multiphysics software. The layered structures include the amorphous silicon c-Si octahedral nanocrystals on the interface SiO2/dielectric were investigated to enhance the SPP inten...

Variation design of open-cell foams located in the bumper car were investigated this paper. A brief experimental result on dynamic response crash was focused energy absorption and deformation behavior. The based typical compared with gradual density hexagonal foam type. method used imitate crashing real behavior explicit using ABAQUS simulation software some extra constraint, such as: object di...

In order to analyze the post-fire seismic performances of scoria aggregate concrete (SAC) beam-column joints precisely and effectively, one finite element model (FEM) was developed simulate behavior SAC joints. The FEM consists two sequential parts: firstly, heat transfer analysis joints, then by combining temperature field distribution obtained from with mechanical properties after fire, both ...

Explosion load studies are an essential part of shield engineering design. This is especially true for explosion-proof plates, which used in order to reduce the impact explosions, have potential cause substantial damage structural elements. The purpose this study detail explosion phenomenon and response sandwich panel structures under explosive loading. finite element method (FEM) model dynamic...

Initial development of a multiscale progressive damage and failure analysis tool for laminated composite structures is presented. The method models microdamage at the lamina level with the thermodynamically based Schapery Theory. Transverse cracking and ber breakage, considered failure mechanisms in this work, are modeled with failure criteria evaluate at the micro-constituent level using the G...

A unified framework is presented that enables coupled multiscale analysis of composite structures and associated graphical pre and post processing within the Abaqus/CAE environment. The recently developed, free, Finite Element Analysis Micromechanics Analysis Code (FEAMAC) software couples NASA's Micromechanics Analysis Code with Generalized Method of Cells (MAC/GMC) with Abaqus/Standard and /E...
