Since scattering and propagation of elastic waves in anisotropic materials are quite different from those in isotropic materials, it is necessary to investigate scattering characteristics for quantitative nondestructive evaluation of anisotropic materials. In this study, a time domain boundary element method is developed with use of fundamental solutions for a general anisotropic solid. The boundary element method is applied to the scattering of elastic waves by various defects such as a cavity and an inclusion, and the radiation patterns and phases of scattering waves are discussed.
