Descriptions
For the criterion of brittle fracture under the mixed mode, Erdogan et al. showed the maximum principal stress theory, and Sih proposed the energy-density-factor (S) theory. The aim of this stydy is to evaluate experimentally the appropriateness these criterions under the mixed mode. The hard polyvinyl chloride rectangular plates with a slant crack are examined in these tests. The initial angles of crack growth θ_<&fnof
