Im vorliegenden Beitrag erfolgt die Diskussion eines mikromechanischen Materialansatzes zur numerischen Simulation der Steifigkeitsreduktion von Werkstoffen. Die Ursache dieser Materialdegradation besteht in der Evolution von Poren ...

With increasing requirements on the crash safety of automotive components and on virtual prototyping it becomes more and more important to model damage behaviour of structural components in crash simulations. Especially high strength ...

The quest for predicting the material failure of ultra high strength steel introduces various approaches in simulations. BTR165 is ultra high strength steel used for safety beams in the vehicles. For the analyses of failure model, ...

The crash behaviour of automobile components from an aluminium die cast alloy and from an extruded profile was characterised under different load conditions and simulated with two damage models (Gurson, Johnson-Cook). The influences ...

A huge amount of effort is spent to develop new materials. To participate the innovation potential of new material property you need to feed you simulations with the appropriate material parameters. Therefore the identification of the ...

This talk gives a brief overview in the topic of crashworthiness and test strategies for High Strain Rate Testing.

The testing system Impetus II provides the automatic analysis of dynamic loaded parts or samples and builds for the first time a closed way of realistic material morphology and load case during test over semi analytical models to ...

The objective of this study is to explore and identify vehicle body design countermeasures to meet the proposed upgrade of the FMVSS 216 standard. Finite Element (FE) methods in LS-DYNA solver are used as a tool to evaluate the ...

Adhesive joints of the car body have to conserve their integrity under crash loading and thus allow the whole structure to consume a large amount of dissipation energy. To meet the respective requirements the glue must exhibit high ...

In general the body-in-white (BIW) consists of thin walled structures joined with adhesives, spot welds, laser welds etc. Due to the efficiency and reliability of laser welding, it is increasingly applied in automotive applications to ...
