Effect of Time Dependent Compressibility on Nonlinear Viscoelastic Wave Propagation.
Abstract
The work presented consists essentially of two parts: the first deals with the development of a nonlinear constitutive equation for a three dimensional viscoelastic material with instantaneous and time dependent compressibility; the second deals with the solution of some specific wave propagation problems for three simple three dimensional geometries. The constitutive equation is based on the existence of elastic and creep potentials and is expressed in terms of single memory integrals with nonlinear kernels. The wave propagation problems are solved by numerical integration along the characteristics of the governing equations.
