LS-DYNA Implemented Fabric Material Model Development for Engine Fragment Mitigation

This document is a proposal for the development and validation of a constitutive material model for Kevlar and Zylon fabrics to be used with the LS-DYNA Explicit finite element analysis program. Modeling dry fabric behavior when subjected to impact loads is a challenging task for a number of reasons. However, a systematic approach can be used in the development of the material model and the model verified with the large amount of experimental data that is available for these fabrics.
