This Part II paper describes a series of constraint-based R6 assessments of shallow-cracked specimens under equibiaxial loading using material constraint parameters obtained from lookup tables presented in the companion Part I paper. Parameters are d

The R6 defect assessment procedure, used commonly in the UK nuclear industry to assess the significance of defects in structures, uses the Failure Assessment Diagram to evaluate limiting parameters whilst accounting for the effects of plasticity. The

This paper provides an overview of developments that have been undertaken in recent years in order to extend the Crack Opening Area (COA) solutions for Leak-Before-Break (LBB) within the R6 Flaw Evaluation Procedures. For high temperature operations,

An alternative definition for the assessment point parameter Kr of the R6 defect assessment procedure is proposed, for combined primary and secondary loading. This alternative definition removes the requirement to calculate a plasticity correction fa

It is well known that material fracture toughness is influenced by factors including loading mode and crack size that influence the level of stress triaxiality ahead of the crack tip. This so-called “constraint effect” has been demonstrated both

Flaw Evaluation, Service Experience, and Reliability.
Parts of the R5 high temperature assessment procedures address creep and creep-fatigue crack growth. The procedures were developed some years ago as separate approaches for creep crack growth (R5 Volume 4) and creep-fatigue crack growth (R5 Volume 5)

This paper presents results from two-dimensional finite element analyses of a centre cracked plate under both plane stress and plane strain conditions. The plate has been loaded in tension and secondary creep conditions have been assumed. The variati
