N2 - The Master Curve (MC) methodology has evolved, from only being a
brittle fracture testing and analysis procedure, to a technological tool
capable of addressing many more structural integrity issues like constraint
and parameter transferability. One issue that not yet has been covered by
the MC is the warm pre-stress (WPS) effect. This effect, which is known to
produce an effective increase in fracture toughness may be of great
importance for some structural safety assessment situations, where thermal
transients are involved. Here, the WPS effect is re-examined and implemented
into the MC methodology.
