Transient processes in shear flow of a viscoelastic liquid. I - Shear wave propagation
Abstract
A two-dimensional problem concerning transient shear flow of a viscoelastic liquid in a half-space with an impulse-driven plane is analyzed within the framework of a generalized Maxwell model for a relaxation time spectrum corresponding to the relaxation properties of polymers. Shear flow between two coaxial cylinders, with the inside cylinder stationary and the outside cylinder rotating at a constant speed, is analyzed numerically using a finite-difference scheme. The effect of the relaxation properties of the liquid on shear wave propagation in the gap between the cylinders is examined.
