Numerical crashworthiness simulation of automotive structures and components made of continuus fiber reinforced composite and sandwich assemblies

Haug, E. / Fort, O. / Tramecon, A. / Watanabe, M. / Nakada, I.

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 rash behaviour of a prototype passenger car compartment structure, made entirely of composite sandwich material
