【Abstract】 Based on Biot theory of two-phase anisotropic media and Hamilton theory about dynamic problem, finite element equations of elastic wave propagation in two-phase anisotropic media are derived in this paper. Numerical solution of finite element equations is given. Finally, properties of elastic wave propagation are observed and analyzed through FEM modeling.更多还原
