Abstract:An accurate staggered finite difference method for modeling elastic waves propagation in transversely isotropic media is presented based on mixed varible stress velocity elastic wave equation and general Hook's law. The method proposed can be applied to the materials with high Possion's ratio and its numerical stability is good. Numerical simulations of elastic waves propagation in homogeneous and heterogeneous transversely isotropic media show that the elastic waves propagation in complex anisotropic media can be modeled effectively by this method and computation costs are very little.
Keywords:elastic wave  difference methods  anisotropy
