REVIEW OF COUPLE-STRESS THEORY OF ELASTICITY AND ELASTIC THEORY OF FRACTURE MECHANICS.

Abstract

The purpose of the research was to study both the stress intensity and the energy criteria of elastic fractures in order to incorporate the couple-stress effect which is induced by high stress gradient. The high stress gradient will be present whenever there is discontinuity in material geometry or constitution. Initial effort was conducted on a systematic reviewing and evaluation of the couple-stress theory of elasticity and the elastic theory of fracture mechanics.
