EFFECTS OF MICRO-STRUCTURE ON THE STRESS CONCENTRATION AT A SPHERICAL CAVITY.

Abstract

In this paper the boundary-value problem for the stress concentration at a spherical cavity in a field of isotropic tension is solved within the framework of Mindlin's theory of an elastic continum with a deformable micro-structure. It is found that the stress concentration factor is moderately larger than the 3/2 of classical elasticity for a wide range of material properties and ratios of radius of cavity to a length parameter of the material - with a critical ratio, nearly independent of the remaining material properties, for which the stress concentration factor is a maximum.
