Abstract
The multiparametric algorithm for solving a fracture dynamics problem is presented in the paper. The linear crack between two dissimilar elastic isotropic half-spaces under normal tension-compression load is considered. The system of boundary integral equations for displacements and tractions is derived from the dynamic Somigliana identity. The crack closure is taken into account by imposing the constraints to the normal components of contact force and displacement discontinuity vectors. The convergence of the algorithm is investigated in detail. The study of the effect of frequency of the loading on the stress intensity factors for opening and transverse shear modes is carried out.
