The study is devoted to the problem for an interface crack located between two dissimilar elastic half-spaces under harmonic external loading. The system of boundary integral equations for displacements and tractions is derived from the dynamic Somigliana identity. The distributions of the displacements and tractions at the bonding interface and the surface of the crack are analysed for the normally incident tension-compression wave taking the contact interaction of the opposite crack’s faces into account. The dynamic stress intensity factors are computed as functions of the frequency of the incident wave. The results are compared with those obtained neglecting the contact interaction.
