## Abstract Several formulations of the Boundary Element Method (BEM) are examined herein in the context of heterogeneous media. A strong singularity develops at re‐entrant interzonal corners and its effect is made more acute by large differences in the material properties. The effects of this sing

Evidence of numerical instabilities in two-dimensional time domain direct boundary element methods is presented. The e!ects of numerical versus analytical integration of spatial integrals on stability are shown, and two new time-stepping algorithms are introduced and compared to existing formulation
