M. Schneider (Salzgitter Mannesmann Forschung) Die Abschätzung der Herstellbarkeit von Tiefziehbauteilen mittels der Finiten-Elemente-Methode ist schon länger Stand der Technik. Die Genauigkeit und die Zuverlässigkeit der ...

In diesem Beitrag wird ein Verfahren zur Detektion von Verzweigungspunkten in unscharfen Tragwerksprozessen vorgestellt. Alle ermittelten reellwertigen Realisierungen eines unscharfen Tragwerksprozesses werden in eine zutreffende ...

The reinforcements of door sills are investigated using both numerical simulations and structural tests. The examinations are based on a test configuration similar to the EuroNCAP pole test which allows to cover the effects of local ...

One of the major tasks in road transportation is to assure an adequate safety level for road users. To maintain and improve road safety, it is often necessary to install certain devices on the road that are intended to restrain ...

This paper describes the development of a new side impact moving deformable barrier finite element model that uses shell elements for aluminum honeycomb. In a previous study, the new modeling method for aluminum honeycomb was applied ...

Simulation of recoverable foams is usually based on hyperelasticity. Since foams are always strainrate dependent, the viscosity of the material has to be considered additionally in the material model. One disadvantage of a viscous ...

Reliable prediction of the behaviour of structures made from polymers is a topic under considerable investigation in engineering practice. Especially, if the structure is subjected to dynamic loading, constitutive models considering ...

This talk gives an overview of ductile damage models in LS-DYNA, an example in implementation of a damage formulation in SAMP as well as gives an insight into an application to a structural part made of thermoplastic material.

This paper describes development of a material model for simulationg crack propagation of casted Aluminum parts. Authors established a new method for predicting the local fracture strain and strength dependent on solidification time ...

The choice of the right material and joining technique in the modern BIW-Design is driven by several factors. The international competition between the OEM’s, new legislations concerning crashrequirements and the current development ...
