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.

Based on some typical fatigue test data for unidirectional composite laminates, residual modulus sequence is found out.
