Simulation Study of the Damage Mechanisms Appearing in a Cross Ply Composite Material Loaded in Uniaxial Tension

The objective of this paper is to predict the different damage mechanisms in multiple scales that can occur a cross ply composite material loaded uniaxial tension. simulated consists four epoxy-glass fibre layers [0/90]s and each layer transversely isotropic with viscous effects occurred from micromechanical homogenization using Mori-Tanaka formulation, extended for visco-elastic materials. For prediction cracking interlaminar delamination, cohesive contacts were used final crack density results compared corresponding experimental ones. Finally microscale analysis was performed Representative Volume Element (RVE) observe matrix behaviour smaller scale.
