Abstract

In the first part of this paper, the Laplace transformed solutions in terms of the generalized ray integrals for point sources in a plate are presented. The inverse transform and the exact solutions for the epicentral responses together with numerical results were given in Part 2. In this part a modified version of Cagniard’s method is applied to obtain the transient response of the plate at any location due to point sources applied at the surface or the interior of the plate. Numerical results are shown for a concentrated force, a single-couple, a double-force, a double-couple without moment and a center of rotation, at locations up to six plate thicknesses from the source.
