The movement towards lightweight mate rials in the construction of automotive bodies is leading to an increase in parts made from extruded aluminum and other materials with a large degree of anisotropic behavior. The need to model ...

While many simulation programs contain sufficient material cards for most of the steel materials, the aluminum cards often aren’t available yet. Therefore many of the aluminum processing suppliers have to create their own cards but ...

This work is concerned with the influence of hypo- and hyper- elasticity on the numerical predictions of the behavior of polymers. A hypo-elastic model applies the rate of deformation tensor as the main kinematic variable, while the ...

This paper proposed a failure criterion of spot welds for combined loading condition for crash simulation. The tests were designed to obtain the failure load of a spot weld under combined loading condition. The seven types of ...

The objective of this study is to develop a finite element model of active human skeletal muscle, which can mimic the contraction behavior of the skeletal muscle and also to analyze the effects of active muscle contraction into ...

The requirements for energy efficiency and lightweight construction in automotive engineering rise steadily. Therefore a maximum flexibility of different materials is necessary and new joining techniques are constantly developed. The ...

Various human head FE models have been developed to clarify the mechanism of Traumatic Brain Injuries (TBIs) and to investigate injury criteria. In most of these models, solid elements are used to model the Cerebrospinal Fluid (CSF). ...

With dramatically rapid development of computing and modelling technology, occupant and pedestrian safety models went through the development of crash test dummies and multi-body mathematical dynamic modelling to finite element ...

The certification process of a fire door implies that the structure is subjected to a standard fire test, to evaluate its resistance to thermal load. In particular, the door must fulfil specific requirements, such as, that the gaps ...

The domain decomposition is important for get the good performance by mpp version. The calculation of ls-dyna is mainly two parts; element calculation and contact calculation. For element calculation, ls-dyna can distribute the ...
