Abstract: The diffraction of elastic wave is studied by using Boundary Element Method, and the formulation about elastic wave diffraction is given. For caculating singular integral, a improved numerical method which divides dynamic fundamental solution into singular part and regular part is proposed. Finally examples of P wave and SV wave scatter against circular hole and ellipse hole are discussed.

Key words: elastic wave, diffraction, BEM, singular integral
