Abstract

The subject of this paper is the one-dimensional, damped wave equation including both viscous damping, where resistance is proportional to velocity, and material damping, where resistance is proportional to displacement.' Disturbances propagating in a material of finite length subject to distributed forces, surface forces and initial conditions will be examined. The purpose of the paper is to develop a numerically accurate and computationally efficient solution using the boundary element method (BEM) and to use this solution to examine the physical behavior of systems subjected to a variety of forcing functions. The model equations are important in both mechanical and thermal wave propagation. The BEM is particularly well suited for th
