The local mechanical properties e.g. flow stress and fracture strain in an automotive component manufactured by deep drawing are inhomogeneous due to different local deformation degrees which affect the component behaviour under crash ...

In the automotive industry, there is an increasing demand for weight reduction as well as safety requirements. These demands have motivated the use of locally optimized components. This study shows how local rigidity of crash-relevant ...

Crashworthiness simulations using explicit Finite Element methods are a central part of the CAE process chain of car body development. Since crash tests of prototype cars at an early development stage are very expensive, a ...

To improve the accuracy of crashworthiness simulation, it is preferable to consider the effects of metal forming. However, this approach was difficult in practice since analyzing the stamping simulation in detail requires much work. ...

The analysis of adhesive bonded joints and structures relies on accurate materials data and mathematical models. In the present study the goal was to develop a method for simulating accurately, using LS-Dyna, the behaviour of ...

The failure mechanism of common aeronautical structures is influenced by the crash behaviour of the riveted joints. Therefore, crashworthiness analyses of aeronautical structures require accurate models of the joints under crash ...

In general, main assembly consists of different sub-assemblies. These sub-assemblies are joined together using rivets/bolts, welds etc. Individual subassembly is often verified for performance using commercial CAE software. To save ...

The light weight potential in automobile fabrication is increasing due to the development of new high strength steels. The realisation of this potential requires the use of adjusted joining techniques for the combination of optimized ...

A growing number of safety systems are implemented in modern vehicles. Thereby vehicles become more complex and in succession the quantity of potential error causes is increasing. Numerical simulation and prototype tests are used to ...

Formula 1 motorsport is a platform for maximum race car driving performance resulting from high-tech developments in the area of lightweight materials and aerodynamic design. In order to ensure the driver’s safety in case of ...
