  • Abstract We first investigate the configurational stability of a semi-infinite crack in the substrate of an isotropic, linearly elastic film/substrate system under residual tension in the thin film. The crack runs parallel to the film/substrate interface. The propagation is found to be generally unstable. We further consider the interaction of the crack, under the same loading, either with a crack in the thin film perpendicular to the interface, or with a finite length interface crack. We… CONTINUE READING
