Implementation of failure criteria for orthotropic non crimp fabric composite structures

Paper i proceeding, 2015

In this paper a set of failure criteria for Non-Crimp Fabric (NCF) reinforced composites are implemented in a Finite Element (FE) software. The criteria are valid for transverse failure of NCF reinforced composites with their inherent orthotropic properties and are used at ply level. Validation of the failure criteria is performed on coupons with features typically found in automotive structures.
