Structural dynamics using Gaussian mass matrix Y. F. Rashed Wessex Institute of Technology, Southampton, United Kingdom Abstract In this paper, a new technique for dynamic structural analysis is presented. The present technique is based on using the dual reciprocity boundary ele- ment method. The inertia term is approximated using the Gaussian radial bases functions. Only the problem boundary is needed to be discretized. Internal degrees of freedom could be added to improve the solution accu- racy. The particular solutions which are necessary to form the mass matrix are derived and given in explicit forms. The singular case is studied and the limiting values of these solutions are derived. An example problem is presented to validate the accuracy of the present formulations. 1 Introduction By the improvements of the structural analysis techniques, it is com- mon nowadays to require monitoring the behavior of a structure under dynamic loading. In the former 30 years, the su
