When the ratio h c / h s of coating and substrate thicknesses is large enough, interfacial debonding can be induced to propagate from the root of a transverse crack under in‐plane loading. An energy balance analysis accounting for the flow rule of the substrate allows translating the load for steady state debonding into an upper bound for the debonding toughness. The method is validated by FEM simulations using a cohesive zone model.
