Abstract
This paper presents a computational (finite element analysis) study for numerically simulating the elastic wave propagation problem in a two-dimensional homogeneous half space. The theoretical formulations of development and implementation of local non-reflecting boundary condition (NRBC) at the soil truncated boundaries has been discussed in detail. A dynamic analysis of the elastic soil domain using time marching scheme has been carried out and comparative studies of the responses from different boundary conditions at the truncated boundaries also has been provided to get the physical idea of the wave reflection phenomena and its absorption capability using NRBCs. The results justify the utility of implementing the local types of NRBC's on the truncated boundaries of the soil domain for solving coupled dynamic problems.
