Abstract
In order to analyze the fracture probability of brittle materials like graphite subjected to multi-axial stress state, where compressive stress is dominant, a new multi-axial distribution function for fracture was derived using series-parallel link model. A brittle fracture loci was analyzed from the above distribution function. A multi-axial fracture test was carried out using isotropic graphite (IG-12) specimen, which were machined to hollow cylinders, by imposing both internal pressure and axial compression. The experimental results showed the validity of the theory.
