The growth of a crack located at the interface between two linearly elastic solids is investigated experimentally. It is found that the crack may advance by kinking into either of the adherends or by propagating along the interface itself, depending on the applied loading conditions. The experimentally observed kinking behavior is compared with analytical results. Agreement between these results is improved by suitable manipulation of a presumably material characteristic crack-extension length, the origin of which is rooted in the linearized analysis. The influence of material rate effects on the crack-kinking behavior is also investigated.
