Fracture mechanics has been applied to the determination of toughness requirements on welded joints of HT80 steel plates, with thickness of up to 100mm, for the huge penstocks of 1000MW pumping up hydroelectric power stations. This paper presents the short introduction of history of establishment of the requirements and makes some discussions on these requirements.
