The influence of finite width interfaces on mixed mode stress intensity factors

Abstract The problem of a crack approaching a finite width interface is investigated using finite elements. The crack is inclined to the interface and a condition of mixed mode fracture exists. The influence of a finite width bond line interface is considered for one representative material pair combination (E2/E1 = 0.10). The stress intensity factors for an inclined crack at various distances from the interface are established as a function of interface width. Maximum cleavage stress and probable angles of crack extension are presented as a function of crack inclination and interface width. Circumferential variations of σrr, σθθ, and αrθ are also presented as functions of crack inclination and interface width.
