Abstract
Three-dimensional finite element simulations of deformation and damage evolution in fiber-reinforced aluminium matrix composites are carried out. The fiber/matrix interface damage is modeled as a finite element weakening in the interphase layers. The fiber cracking is simulated as the damage evolution in the randomly placed damageable layers in the fibers, using the ABAQUS subroutine User Defined Field. The effect of matrix cracks and the interface strength on the fiber failure is investigated numerically.
