Fracture Problems in Power Law Viscoelastic Materials.

Abstract

This report summarizes progress on several theoretical questions concerning contact and fracture phenomena for viscoelastic material. Specifically, the following topics are discussed: (1) the dynamic, steady-state propagation of a semi-infinite crack in a general, isotropic and homogeneous linearly viscoelastic layer of finite thickness; (2) the determination of the angular dependence of the stress field in the neighborhood of a dynamically propagating crack tip in linearly viscoelastic material; (3) the quasi-static and steady-state sliding of a rigid indentor over a power-law inhomogeneous, linearly viscoelastic halfplane; and (4) the quasi-static propagation of a semi-infinite, mode I crack in a power-law inhomogeneous, linearly viscoelastic body.
