The present paper outlines basic material models for composite strength and failure analysis, based on ESI's PAM-FISS/Bi-Phase composite material model. The new material models have been ported into the PAM-CRASH™ crashworthiness simulation code and applied to the crashworthiness simulation of axially compressed box columns made of hybrid Carbon-Kevlar-Aramid sandwich walls. After calibration of the models on laboratory coupon tests and validation on simple component crash tests, the methodology can be used to predict the crash behaviour of a prototype passenger car compartment structure, made entirely of composite sandwich material.
