摘要：

Recent studies have shown that for a variety of unirradiated and irradiated materials, a slope of similar to 2 is obtained for a correlation between yield in a shear punch test and yield in a uniaxial tensile test. Application of the von Mises yield criterion would predict a slope of root 3. A finite element model (FEM) of the shear punch test was developed to aid in understanding the experimentally obtained slope of similar to 2. FEM simulations of the sheer punch test were conducted using stress-strain data from uniaxial tensile tests on 316 stainless steel in four initial cold-work conditions. A correlation was developed between the FEM-evaluated effective sheer yield strength and the experimentally-evaluated uniaxial yield strength. The slope from this correlation was found to be nearly the same as for the slope from the correlation between the experimentally-evaluated effective shear yield strength and the experimentally-evaluated uniaxial yield strength. The finite element model showed that stresses other than pure shear exist in a specimen during a shear punch test, and these other stresses may explain why the slope of the experimental yield strength correlation is different than root 3.
