Examples of damage mechanisms are corrosion under insulation, brittle fracture, thermal fatigue, and heat damage. The damage mechanisms library is used to define generic failure modes outside of the context of an RBI analysis. When performing RBI analyses, the analysis team can browse the library, select failure modes, and add them to the analysis. Once a failure mode is copied to the analysis, the team is guided by the information on it. In most cases, they can change the information as needed. Note: The damage mechanisms library contains only RBI failure modes, and they can be added only to RBI analyses. The topics in this section explain how to set up the information used in damage mechanisms. Note: You can set up material types, barrier types, technologies, and usage groups from both the Damage Mechanisms and Failure Modes tabs.
