Abstract

The paper describes the development of a material model, which allows for anisotropy of elastic constants, the yield surface, work hardening parameters and damage. The current failure/damage model is porosity based and allows for the modelling of tensile failure and includes the effect of anisotropy. The model accounts for non-linear behaviour at high pressures, and is implemented in the LLNL-DYNA3D. The importance of the above mentioned model features when considering the response of anisotropic materials to high strain-rate loading is illustrated by considering two examples, flyer plate impact and Taylor cylinder impact.
