EVOLUTION OF THE FRONTS OF QUASI-COMPRESSIONAL AND QUASI-SHEAR DISCONTINUOUS WAVES IN INHOMOGENEOUS TRANSVERSELY ISOTROPIC ELASTIC MEDIA

摘要

The propagation and evolution of the fronts of discontinuous waves in inhomogeneous transversely isotropic elastic media are studied. A method to draw evolving rays and fronts is proposed. Geometrical singularities on the fronts are studied for different parameters of anisotropy and inhomogeneity
