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
