forward by KELLY, TYSON and COTTRELL, the primary reason for the occurrence of a little plastic yield during the cleavage course is that the shear yield strength is not much smaller than the tensile fracture strength, so the plastic yield occurs when the stress reaches shear yield strength, and the brittle fracture occurs when the stress reaches tensile fracture strength. 3.2 Influence of relative......
