In this paper, interior flux calculations for two-dimensional transient scalar wave propagation are developed and presented for the first time in the BEM literature. There are some severe analytical difficulties in the derivation of these kernels which have been circumvented through physical interpr

The transient Green's function of the 2-D Lamb's problem for the general case where point source and receiver are situated beneath the traction-free surface is derived. The derivations are based on Laplacetransform methods, utilizing the Cagniard-de Hoop inversion. The Green's function is purely alg
## Abstract Nonβoverlapping domain decomposition techniques are used to solve the finite element equations and to couple them with a boundary element method. A suitable approach dealing with finite element nodes common to more than two subdomains, the soβcalled crossβpoints, endows the method with
In this paper a new technique is presented for transferring the domain integrals in the boundary integral equation method into equivalent boundary integrals. The technique has certain similarities to the dual reciprocity method (DRM) in the way radial basis functions are used to approximate the body
A linear y method is used in this paper to improve the stability of the standard time-domain BEM formulation. The time-stepping procedure is similar to that of the Wilson y method; however, unlike in the FEM, where linear time variation of acceleration (for elastodynamic problems) is assumed, here l
