dc.description.abstractThe purpose of this research is to develop a fully-tabulated, anisotropic, asymmetric, strain rate, and temperature dependent material model for solid finite elements. Physical testing of several metallic materials has shown to have anisotropic (or orthotropic) characteristics. While many material models in finite element codes currently have anisotropic options, they tend to focus on material forming applications – not crash and impact analysis. Unlike most anisotropic forming material models, this model has: rate dependency, temperature dependency, tabulated hardening (as opposed to parameterized inputs), associated flow, and the ability to maintain numerical stability for large deformations.
