Because some of these materials are susceptible to rapid fracture resulting from small flaws, sub-critical crack growth aspects of material behavior, such as stress-corrosion cracking and fatigue, should be reviewed as a part of the design process, preferably as part of an overall fracture control plan. Experience suggests that the development and implemenation of such a plan as part of the design process will result in a more balanced design from the standpoint of safety, reliability, and economics.
