The fatigue behavior of a composite laminate is first characterized by initiation and multiplication of the cracks rather than by their quasi-instantaneous growth. Cracks multiply during the cycles until reaching a saturation state. This phenomenon was first modeled by Reifsnider [1] and Garret and Bailey [2]. In this approach to transverse cracking under fatigue loading, the cracks are assumed to have the same geometric characteristics as those occurring under quasi-static loading [3]. In particular, it is assumed that they go through the thickness of the plies and that their propagation is quasi-instantaneous
