For high frequency analysis, Statistical energy analysis (SEA) has proved to be a promising approach to the calculation of sound transmission in complex structures. In automotive industry and also in civil engineering, most of ...

For those who spend a lot of ti me driving, issues of comfort can become issues of health and safety. Therefore seating comfort is an important point in the seat development. Currently, the OEM and Tier - 1 are ...

The most generally accepted tool for the assessment of formability of sheet material up to the present date is the forming limit diagram (FLD). It allows the identification of critical areas in a sheet - forming simulation where ...

Responding to continuous demands for weight saving and enhancement of collision safety of vehicles, high-strength steel sheets are widely used for car bodies. Also, the applications of aluminum sheets are increasing for seeking ...

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 ...
