Abstract: Absorbing boundary conditions are required to simulate seismic wave propagation in elastic media. In the first part of the paper, a number of relevant ABCs are reviewed with emphasis on practicality and ease of implementation. The second part of the paper describes the derivation of a new user element for seismic analysis in ABAQUS/Standard. The element is a combination of two ideas: ...

Abstract: In this study, carried out by fka, the hood of the VW Golf V is taken as an example to analyze the potential of a hybrid construction of aluminum and steel. Structural stiffness, oil canning and dent resistance behavior are analyzed using Abaqus/Standard. With the objective of reducing the total hood weight, the performance of the hood is compared to reference values of the series pro...

The Taurus has a MacPherson strut type of suspension in the front and rear of the car, as shown in Figure 1. The various types of joints in the suspension are modeled with connector elements. These specialized elements provide an easy and versatile way to model physical mechanisms with point-to-point connections that can exhibit complex kinematic and kinetic relationships. A list of model joint...

In this study, we propose the first unified implementation strategy for peridynamics in commercial finite element method (FEM) software packages based on their application programming interface using peridynamics-based (PeriFEM). Using ANSYS and ABAQUS as examples, present numerical results details of PeriFEM FEM software. is a reformulation traditional solving peridynamic equations numerically...

This paper presents a constitutive model capable of predicting the anisotropic viscoelastic behavior of balloon film subject to large strains and cyclic loading. The model is based on the free volume theory of nonlinear viscoelasticity enhanced with a switching rule for treating loading and unloading differently. The model has been implemented in the finite element analysis program Abaqus/Stand...

Finite-element simulation of the hot pressing process has been performed using ABAQUS. The viscoelastic polymer (polymethyl methacrylate) used in this study has mechanical properties that depend on the temperature and working pressure. Based on the nonlinear viscoelastic model, the polymer material behaviour is simulated successfully with the data obtained from material tests. Simulation result...
