Boundary element method solution in the time domain for a moving time-dependent force

The problem of a moving time dependent concentrated force on the surface of an elastic halfspace is of interest in the analysis of traffic generated n oise. The Boundary element method (BEM) is superior to the Finite element m ethod (FEM) in solving such problems due to its inherent ability so satisfy the radiation conditions exactly. In this paper a model based on the BEM i s formulated for the solution of the mentioned problem. A numerical solutio n is obtained for the 2D plane strain case. and comparison is made with the results obtained from a corresponding FEM solution with an impedance absor bing boundary condition.
