This talk discribes the recent enhancements to the GISSMO Failure Model in LS-DYNA.

A transversely isotropic elastic-viscoplastic constitutive law with a novel 3D failure criterion is presented, addressing high pressure effects, strain rate sensitivity in yielding and failure and volumetric plastic strain. The ...

For predicting the containment safety of turbochargers against failure of rotors at elevated temperatures and dynamic loading the complex deformation and damage behaviour of the respective materials has to be determined by appropriate ...

One of the most important factors in ensuring the adequacy of the mathematical modeling of limiting states of structures is the choice of the material local fracture criterion and accurate determination of its parameters. The paper ...

When investigating the limiting states of materials under dynamic loading conditions, it’s important to specify the dependency of plastic failure strain on the stress state. Usually, such dependence is build upon the experimental data ...

This presentation gives an overview of RHODIA Polyamide, MMI ConfidentDesign as well as presents the MMI Beam and discusses the correlation using DIGIMAT to LS-DYNA.

Integrative simulations are based on a calculated bre orientation from which the local material properties can be derived in several ways. For instance the micro-mechanical model proposed by Tandon and Weng may be used coupled with ...

For the predictability of composite material behaviour under highly dynamic loads like crash, there is a need for better models reproducing the exact physics of failure mechanisms (matrix cracking, delamination, heat dissipation ...

The quality of the mechanical simulation of reinforced thermoplastics depends on very com­ plex input parameters regarding the complex material behaviour. At the beginning of the sim­ ulation chain the material data has to be ...

This paper investigates low velocity impact involving a glass fibre-reinforced polyamide engine oil pan as part of a complete new development of thermoplastic components. The assessment of the impact resistance has driven the need to ...
