1. Introduction
Delamination is the separation of plies and is one of the most detrimental modes of failure in the composite materials. Delamination can be initiated by cyclic loading, impact, stresses near free edges, manufacturing defects like incomplete wetting or the presence of transverse matrix cracks. Delamination can grow under fatigue loading and lead to reduction of stiffness, lowering of critical buckling load and complete failure of the structure. Accurate modeling of delamination growth under fatigue loading is essential to safe design of composite structures exposed to cyclic loading such as wind turbine blades and aircraft wings. For the case of small-scale yielding at the crack front, Paris equation has been successfully used to describe crack growth under cyclic loading. First proposed by Paris et al. [1,2], this equation is usually presented in terms of either stress intensity factor or energy release rate:
