This document specifies methods for determining fracture toughness in terms of stress intensity factor
(K), crack tip opening displacement or CTOD (δ) 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 determining point values of fracture toughness. It should not be considered a way of obtaining a
valid R-curve (resistance-to-crack-extension curve). However, the specimen preparation methods
described in this document could be usefully employed when determining R-curves for welds. The
methods use fatigue precracked specimens which have been notched, after welding, in a specific target
area in the weld. Methods are described to evaluate the suitability of a weld for notch placement within
the target area, which is either within the weld metal or within the weld heat-affected zone (HAZ), and
then, where appropriate, to evaluate the effectiveness of the fatigue crack in sampling these areas.
