Abstract
In this work, integral representations (displacement and stress components) for time domain bi-dimensional elastodynamic boundary element analyses are written by making use of, the concept of finite part of integrals. Linear elements are used to discretize the boundary. Displacement and traction components are respectively assumed to have linear and constant variation in time and the time integration is carried out analytically. Time integrated kernels depend on the position of the wave front and the boundary integration follows the usual pattern of the method. An assessment of the accuracy of the results provided by this BEM formulation can be seen at the end of the article.
