G0310304 Stress Intensity Factor for Anisotropic Elastic Cylinder with a crack

Abstract

Brittle failure of the structure such as a bridge, large tank and warship sometimes can be caused by the cracks. In the past century, many human life were lost and physical damages were caused in these accidents. To explain brittle failure phenomena, linear fracture mechanics are established by Irwin et al. based on brittle failure theory proposed by Griffith. In fracture mechanics, new parameters named 'Stress Intensity Factors (SIFs)' were introduced since that parameters are nearly constant if different size pieces are broken by any loadings. For the isotropic materials with cracks, SIFs are obtained by many researchers, and Tada summarized these analytical solutions. In this paper, SIFs for Cylinder with cracks subjected any loadings, for example, splitting force, on the lateral side of a cylinder are derived by using constraint release technique and some numerical examples are shown graphically. It is assumed that a cylinder behaved as anisotropic elastic body.
