Abstract : High-strength structural alloys and weldments, such as those used in ship construction, can be exposed to deleterious environments under load and can experience environmentally assisted cracking (including stress-corrosion cracking and corrosion fatigue) during service. Designers cannot now anticipate with confidence a material's susceptibility to environmentally assisted cracking or determine how to characterize and incorporate such information in the design process (i.e., to quantitatively assess durability and reliability).
