The Effect of Interface Damage on Macroscopic Constitutive Behavior of Composite Materials
Base on the finite element method, the effect of interface damage on macroscopic constitutive behavior of composite materials subjected to uniaxial tension was studied. A bilinear cohesive law, which relates the traction and displacement jumps, was adopted to model the debonding of particle/matrix interface. Stress-strain curves for a material with different interface properties, particle size and volume fraction were discussed in detail. The results show that the damage due to debonding of particle/matrix interfaces can significantly affect the macroscopic response of composite materials, and that the interaction of particles is innegligible in multi-particle structure.
