Metallic materials. Method of test for the determination of quasistatic fracture toughness of welds Ingestion-build-68772 BS EN 81‑28:2018 includes some1 Scope This document specifies methods for determining fracture toughness in terms of stress intensity factor (K), crack tip opening displacement or CTOD () and experimental equivalent of the J integral for welds in metallic materials (J). This document complements ISO 12135, which covers all aspects of fracture toughness testing of parent metal and which needs to be used in conjunction with this document. This document describes methods for
