Abstract : The recently evolved Ratio Analysis Diagram (RAD) procedure is a useful engineering tool for generalized assessment of the fracture resistance of high-strength steels. Failure-safe design of large complex structures also requires consideration of subcritical crack growth caused by stress-corrosion cracking (SCC). Procedures developed to incorporate SCC characterizations into the RAD concept provide a more complete analysis of a material's resistance to fracture. The SCC-Dual RAD for high-strength steels presents simplified interpretations of the critical flaw size-stress instability conditions for both slow fracture (SCC) and fast fracture of these materials.
