This paper presents a convolution quadrature time-domain boundary element method for 2-D elastic wave propagation in general anisotropy. Boundary element method (BEM) is well known as an effective numerical approach for wave propagation problems. However, the conventional time-domain BEM has a critical disadvantage: it produces unstable numerical solutions for small time step size. To overcome the disadvantage, we develop a new time-domain BEM based on the convolution quadrature method (CQ-BEM) for 2-D general anisotropy. As numerical examples, the problems of elastic wave scattering by a cavity are solved to validate the present method.
