This paper introduce CAE design tool to calculate the singular values by FEM stress results near singularities. This tool made by Excel VBA. First, create a line graph of any direction after reading a stress results file based on FEM analysis. Second, calculate the stress singularities of each line from the profile of the stress distribution. From the values and the direction, we can evaluate the fracture strength and fracture direction at stress singularity field.
