Abstract: 

In this paper, formulation of a two-dimensional hybrid finite / boundary element method is developed for wave propagation analysis of linear elastic media in time domain. A modified set of well behaved full space two-dimensional elastodynamic convoluted kernels is presented and employed, that has a higher degree of accuracy than those presented by the previous researchers. Applicability and accuracy of the hybrid method are established by investigating seismic responses of half-plane, canyon and ridge sections as well as an underground explosion.
