Implementation of failure criteria for transverse failure of orthotropic Non-Crimp Fabric composite materials
Artikel i vetenskaplig tidskrift, 2017
In this paper a set of failure criteria for Non-Crimp Fabric (NCF) reinforced composites is implemented in
a Finite Element (FE) software. The criteria, implemented at the ply level, predict transverse failure of NCF
reinforced composites, in particular accounting for their inherent orthotropic properties. Numerical
simulations are compared with tests on specimens with a generic design feature found in automotive
structures. The current implementation enables correct prediction of failure mode and location.
