Mode III Interface Crack Lying at Thin Nonhomogeneous Anisotropic Interface. Asymptotics Near the Crack Tip
Mode III problem for the interface crack tip lying at various nonideal (imperfect) interfaces in dissimilar elastic body is investigated. Nonclassical transmission conditions described by features of thin nonhomogeneous anisotropic elastic layer situated between the matched materials are discussed. For this aim, an accurate asymptotic technique is applied. Asymptoptic expansions of elastic solutions in three di erent cases (soft, stiff and comparable in values interphases) are obtained. It is shown that the asymptotic approximation depends essentially on types of the interface as well as its local geometrical and mechanical properties.
