THE BOUNDARY ELEMENT METHOD FOR SCATTERING OF TRANSIENT WAVE FOR ANISOTROPIC MEDIUM

A set of boundary integral equation (BIE) of transient waves scattering in an anisotropic medium is established by Fourier transformation and weighted residuals method, and an appropiate shape-function is also obtained in this paper. Several examples calculating the scattering displacement show that the method used for scattering high-frequency transient wave is effective.
