摘要

This joint topic between Codes and Standards (C&S) and Materials and Fabrication (M&F) provides a summary of recent developments of stress intensity factors solutions and their applications to various codes. There are three sessions in this topic - two in C&S (CS-26-1 and CS-26-2) and one in M&F (MF-9-1). There are four papers in Session CS-26-1. The paper by K. Azuma et al focuses on surface cracks with large aspect ratios. They evaluated the stress intensity factor interactions between adjacent cracks and proposed a flaw combination rule based on flaw length rather than flaw depth. The paper by C. Faidy provides a comparison between the stress intensity factor solutions provided in French RSE-M, Appendix 5 and in ASME Code Section Ⅺ. The paper by D.J. Shim et al provides the validation of stress intensity factor solutions in xLPR Version 2.0 code. The predicted fatigue crack growth results using the xLPR solutions are in good agreement with the experimental data. The paper by P. Dulieu et al provides some benchmark calculation results of quasi-laminar elliptical crack interaction under bi-axial loads using the FE alternating method and X-FEM.
