It is well known that ductile failure of metal is occurring after a certain amount of plastic deformation. Therefore, knowledge about the deformation behavior of materials is required to understand damage processes and to describe the ...

FEM simulation to assess formability and crash performance is used increasingly in automobile industry in order to reduce development time of complete new vehicle models and platforms. The simulations give the finite deformation ...

In this paper, we present a methodology for the multiscale analysis of deformation and failure of partially sintered metals. This methodology is based on experimental investigations, mesoscale modeling with the finite element method ...

This talk introduces into the topic of "Multi-Scale Modeling of Crash and Failure of Reinforced Plastics Parts with DIGIMAT to LS-DYNA Interface".

The new continuum damage model is based on a general thermodynamic framework for the modeling of rate and temperature dependent behavior of anisotropically damaged elastic-plastic materials subjected to fast deformation. The ...

Thermoplastic polymers reinforced with mineral (talc) particles typically display an anisotropic mechanical behavior that results from the preceding manufacturing process (e.g. injection moulding) with a distinctive direction of melt ...

The virtual estimation of physical product properties is only as good as the virtual description of the behaviour of its material. On the one hand there are well known material cards like *MAT_PIECEWISE_LINEAR_PLASTICITY in LS-DYNA© ...

This paper describes hip sliding mechanisms for seating comfort evaluation using a human FE model (THUMS). From a rigid seat experiment, combined with THUMS simulation, it was first found that the backward moment around the hip centre ...

This presentation of the study includes background-objectives, material modeling as well as validation and a conclusion.

The lower limb is one of the most frequently injured body regions in crashes involving pedestrians. A biofidelic FLEXible-Pedestrian Legform Impactor Global Technical Regulations (FLEX-PLI GTR) device has been developed under ...
