Interaction of two unequal cracks in a prestressed fiber reinforced composite

Abstract

We consider an elastic orthotropic material representing a fiber reinforced composite. The composite is prestressed and contains two collinear cracks having different lengths. The faces of the cracks are acted by symmetrically distributed constant normal incremental stresses. We determine the critical values of the applied incremental stresses for which the cracks tips start to propagate and we analyse the interaction of the cracks as function of their lengths and of the distance between the cracks.
