Abstract

On the base of the model of an elastic deformation of isotropic materials that characterized by different resistance under tensile and compression loading, the problem of propagation of longitudinal and transverse elastic waves in powder materials containing flat defects was considered. It was established the relations between velocities of longitudinal and transverse elastic waves and defect content and mode of deformation.
