摘要
This work presents a boundary element method formulation for the analysis of scalar wave propagation problems. The formulation presented here employs the so-called operational quadrature method, by means of which the convolution integral, presented in time-domain BEM formulations, is substituted by a quadrature formula, whose weights are computed by using the Laplace, transform of the fundamental solution and a linear multistep method. Two examples are presented at the end of the article with the aim of validating the formulation. (C) 2002 Elsevier Science Ltd. All rights reserved.
