State of the art in constraint based fracture mechanics

Important outputs from VOCALIST are the D5 and the D12 reports. The first of these, D5, "Issue 1 of the Handbook of Best Practice for Application of Constraint-Based Structural Integrity Procedures" presented the main issues and current state-of-the-art techniques as they existed at the commencement of the VOCALIST project. D12, "Issue 2 of Handbook of Best Practice for Application of Constraint-Based Structural Integrity Procedures", is essentially an updated version of D5, which incorporates the experimental and analytical results obtained from the VOCALIST Work Packages described in detail in other Results sections, and gives more recent advice.

These documents, especially the latter, are of benefit to engineers who have responsibility for using defect assessment procedures or for managing and planning R&D programmes designed to improve or extend defect assessment technology.

A wide range of techniques are discussed, including two-parameter constraint based fracture models, energy approaches, failure assessment diagram approaches, the Master Curve statistical method for analysis in the ductile-to-cleavage transition region, and the application of Local Approach methods. Advice and the experience developed by or known to the participants is documented. References are given to articles in the open literature relevant to a wide range of influential developments are also given. The Reports are therefore effectively compendia of information of considerable practical utility.
