Нашла нечто похожее на мою тему:
In the last decades, there has been a move away from “workmanship” criteria, where defects were accepted or rejected primarily on what the inspection system could detect, to “Fitness-For-Service” (FFS) criteria, which are based on Fracture Mechanics (also called Engineering Critical Assessment, or ECA). FFS uses the material toughness, crack growth data and the component duty cycle to estimate the service life, and hence acceptable initial defect size.
