摘要：
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 equation the integral equation for velocities. Numerical examples are presented in order to assess the accuracy of the proposed formulation. (C) 1998 John Wiley & Sons, Ltd.
