Additional information
Numerical results have shown that current methods for treating secondary stresses in fracture codes can be over conservative in some cases where there is no elastic follow-up but non-conservative in cases with significant elastic follow-up. This paper derives a theoretical framework which covers both of these cases and therefore provides a rational basis for updating fracture assessment methods. The results have been used to draft revisions to the R6 defect assessment procedure and the proposed revisions are currently being assessed against a wide body of numerical and experimental data.
