Abstract

In this paper we consider a region of damage as a region of the material in which the elastic constants have substantially smaller values than in the undamaged state. The reduction of the elastic constants may be due to void distributions, zones of plastic deformation, microcracking and other generally continuous distributions of inhomogeneities which have a deleterious effect on the stiffness and presumably also the local strength of the material.
