Development of Characterization of Failure Modes for Mechanical Components

A database-driven approach is needed which characterizes the failure modes of the mechanical components of submarine systems under extreme loadings. Such an application must provide automation of the component shock qualification process through an automated capability while providing component-level qualification based upon similarity of components and failure modes. Certification of shock worthiness of new components may then be deduced through an"extension"process (in which new components that are similar in physical aspect, shipboard installation and intended use, to a previously"qualified"component) and may be certified based upon the certification of those similar components. Leveraging rules with a software reasoner allows for the automatic generation of new facts such as certification through the extension process.
