Abstract
Finite element techniques are often used to analyze plate structures for brittle failure. If the fracture analysis diagram is taken as the failure criterion, then the special post-processing scheme offered herein becomes an effective analysis aid. This paper suggests contour plots of allowable flaw size as a viable scheme and demonstrates the effectiveness of this approach with two examples.
