Discrete element approach to simulate debonding process in 3D short glass fibre composite materials: Application to PA6/GF30

This paper discusses the development of a numerical approach based on the Discrete Element Method (DEM) to simulate the interfacial debonding in Short Fibre Reinforced Composites (SFRC). For that purpose, we consider a hybrid lattice-particle approach based on a cohesive beam model. Already used to study composite materials, we aim to extend this concept to investigate the damage mechanism of SFRC in particular the PA6/GF30. To do so, a specific...
