1426 Numerical Solution for Two-Dimensional Elastic Wave Problems by Use of the Combination of the Fast Fourier Transform and the Characteristic Methoed

Abstract

The object of this article is to study the numerical methods for solving two-dimensional elastic wave propagation problems. The method involves the use of the combination of a Fourier transform for one space variable and the characteristic method for the other space variable. An example problem is presented which involves transient waves in an elastic plate subjected to the impulsive stress acting on its top surface.
