摘要

This paper is concerned with numerical analysis of the transient elastodynamic problems by the dual reciprocity BEM (DRBEM) in space combined with the differential quadrature method (DQM) in time. Emphasis is placed on a comparative study of various time- marching schemes. Three numerical examples considered are for the longitudinal forced vibration of plates and the transverse free vibration of membranes.
