The complete expressions corresponding to space and time derivatives of Volterra's integral representation of the time-dependent scalar wave equation are presented in this paper. The concept of finite part of an integral is used in order to compute boundary kernels contributions. Time integration of

In the present paper the traditional BEM formulation for time-domain scalar wave propagation analysis is extended to a new class of problems. A procedure to consider linear time interpolation for boundary tractions is worked out. Time discontinuities are included by adding to the standard BEM equati
