The damage represents complex mechanism. In this research based on T300/HT3 laminate structure, fatigue life is predicted phenomenologically, dealing mainly with in-plane stresses without accounting for out-of-plane failures such as craze. Fatigue modulus, based on damage mechanics, is used as a physical parameter which helps to describe the basic fatigue behaviors of unidirectional laminates and obtain expressions for cumulative damages defined by strains and stress. Based on some typical fatigue test data for unidirectional composite laminates, residual modulus sequence is found out.
