heal.abstract	This paper continues earlier research on the performance of several consistent mass matrices for the boundary element method (BEM) dynamic analysis (wave equation problems), examining now the applicability of lumped mass matrices for several BEM formulations. In the beginning, the lumped masses are distributed along the boundary and three relative BEM formulations are proposed. Finally, the lumped matrices are introduced into the Partial Differential Equation (PDE) as Dirac-type domain inertial terms. © 1993.	en
