Identifying failure initiation in automotive structures made of NCF reinforced composites for hot spot analysis
Paper in proceeding, 2016
In this paper, intrabundle failure initiation in NCF reinforced composite materials is predicted based on a finite element model built with shell elements. The full 3D stress state is estimated based on the shell results and used in a state of the art 3D failure criterion. The procedure considers predictions of the transverse shear and normal stresses from stress equilibrium. By using this approach on shell elements, more efficient modelling strategies suited to identify hot spots in larger structures can be pursued.
