Treatment of residual stress in fracture assessment: background to the advice given in BS 7910:2013

摘要

The UK procedure for fracture mechanics-based assessment of flaws (BS 7910) was extensively updated in late 2013. This paper outlines how and why the clauses and Annexes relating to residual stresses (in particular those arising from the manufacturing of welded joints) have been expanded, and explains the origin and extent of validation of the information. A worked example of applying the guidance to fracture assessment of a welded joint is included.
