The use of math-based tools has reduced the need for hardware prototyping and testing, which in turn reduces a vehicle’s development time and cost. LS-DYNA has been extensively utilized in the crashworthiness community to improve ...

This talk gives an overview of material and component tests as well as sled tests, barrier design and abdomen calibration regarding dummy validation.

This presentation covers scripting with Javascript in Oasys PRIMER and Oasys D3PLOT.

Viscoelastic effects have a wide influence on the behaviour of long-term loaded components. Considering this characteristic behaviour of polymer materials appropriate material models have to be used in FE-simulations. LS-Dyna provides ...

For the finite element simulations of polymeric materials mathematical models are needed which cover all the phenomena of the material. In the first part of this paper a new model based on the invariant theory is introduced. With this ...

The paper presents a computational study of adhesively bonded metallic hollow sphere structures fully embedded within an adhesive matrix. Their behaviour under compressive dynamic loading was evaluated by means of dynamic ...

Due to their excellent mechanical properties sandwich panels with carbon fibre reinforced plastics (CRFP) face sheets and folded core structures are very interesting for future aircraft fuselage concepts. The complex failure behavior ...

The impact behaviour of fibre-reinforced composite materials is much more complex than it is for conventional metallic structures due to a number of different failure modes on the interlaminar and intralaminar level. In most of the ...

The numerical simulation of the crash front in composite structures is up to now still difficult. To improve the numerical results a so called ‘stacked shell’ model for laminated composites which is typically used for impact modelling ...
