Stress-corrosion cracking (SCC) involves the interaction between stress and the environment to cause cracking in situations where if present independently their effect would be benign. SCC involves mechanics through the role of stress and the material through its interaction with the environment. SCC has occurred in many engineering structures, generally without expectation that a specific combination of material and environment would produce such cracking. This paper discusses SCC and the development of models to quantify its effect on the life of structures—outlining both the approach and inherent complications due to the coupled mechanics and materials issues. This development is illustrated with reference to characterizing the initiation and early growth of SCC as it occurs on gas-transmission pipelines. The discussion closes with consideration of failure criteria for use in this application, which involves the coalescence of several cracks with the rather complex patches of cracks that occur with SCC in this application. Areas needing further attention are identified.
