Development of Fracture Assessment Standards in Japan with Weibull Stress
This paper describes the fracture assessment standards developed in Japan, where the Weibull stress is implemented to correct the CTOD toughness for constraint loss in structural components. ISO 27306 and WES 2808 (Japan Welding Engineering Society Standard) are presented. Discussion is given on the effects of strength mismatch and residual stress in welds.
