Abstract

Abstract:

Neuber s formula is analyzed in this paper. It is found that Neuber s formula is not an analytical solution even to the antiplane shear loading problem. By using the theory of elastic-plastic fracture, an elastic-plastic stress-strain concentration formula is obtained for antiplane shear loading crack problem of power hardening materials.

Key words: Elastico-plasticity, Strain, Stress analysis, Fracture, Mechanics
