In this paper, we investigate the effects of the hierarchical wavy morphology of an interface on the apparent interfacial fracture toughness. First, the influence of two-level hierarchical sinusoidal geometry under mode-I and mode-II far-field loadings on crack propagation behavior is numerically studied by using a cohesive zone model. Second, the effects of interfacial friction on the mode-II effective fracture toughness are examined. The results show that an interface with a hierarchical...[Show more]
