N2 - A general orthotropic material model has been developed which is suitable for impact analysis. The material model is driven by tabulated data rather than point-wise material properties data, and has been implemented into LS-DYNA. The stress-strain behavior of a material is one of the input tabulated data used to drive the material model which can be obtained either from experiment or virtual testing or a combination of both. The material model consists of three sub-models – deformation, damage and failure. The implementation of the sub-models and some of the salient features are presented in this paper. The second part of the paper presents some of the validation tests carried out using a unidirectional fiber reinforced composite, T800/F3900.
