Delamination of a bi-material strip by a steady-state interfacial crack

Abstract

Steady-state moving Mode-III infinite interfacial crack along the perfect interface in a dissimilar strip is investigated. The crack position is not generally speaking symmetrical with respect to the strip surfaces. Both Dirichlet and Neumann external boundary conditions are considered. Asymptotic behaviour of the solution is analysis with a special emphasis to the value of stress intensity factor as function of the crack velocity and material and geometrical properties.
