—A bi-material element composed of two plates bonded by an interface and subjected to monotonically increasing loading is considered. The cohesive zone model is assumed to simulate the interface response in shear. The coating layer response is characterized by the critical failure stress. The layer cracking modes are analyzed by applying the shear lag approach. The analytical solution illustrates the effect of strength on cracking of the coating layer.
—Fragmentation, cohesive zone model, shear lag model, mechanical loading.
