SHRINKAGE STRESSES IN CASE-BONDED VISCOELASTIC HOLLOW CYLINDER OF INFINITE LENGTH,

Abstract

Stresses and strains in a thick-walled cylinder of viscoelastic material of infinite length due to homogeneous shrinkage or swelling of the material are discussed. Two models, one of which assumes a standard solid response in shear and elastic response under volumetric strain, the other standard solid response for both conditions, are employed in order to demonstrate the effect of volume viscosity. Two different (initial) Poisson's ratios are considered to find the effect of the elastic compressibility of the viscoelastic material. The first invariant of the stress tensor and a measure of triaxiality are also computed because of their assumed sensitivity with respect to crack initiation in viscoelastic materials. (Author)
