N2 - Equations describing the growth of internal delaminations under cyclic loads are obtained on the basis of a combined delamination buckling/postbuckling and fracture mechanics model. The results show that for the same delamination thickness, h, the fatigue delamination growth is strongly affected by the relative location of the delamination through the plate thickness, T, the fatigue growth being slower for a smaller value of h/T. These theoretical predictions are confirmed by experimental results that are obtained for the growth of delaminations in graphite/epoxy unidirectional specimens under cyclic constant amplitude compressive loading.
