Time-domain boundary element method formulations (TD-BEM) are quite versatile in reproducing the transient response of finite and semi-infinite solid media and offer a number of advantages compared to transformed domain (Fourier or Laplace) approaches. They are known, however, to be prone to numerical instability, especially after a very large number of time steps. This seems to be more of a problem with 1D as compared to 3D formulations, although it is present in the latter ones. A careful investigation of the problem reveals that if the conventional BEM formulation using displacement and traction variables is replaced with one using velocity and traction pairs, the problem is ameliorated to a large extent and much better accuracy results.
