Efficient analysis for FMEA [Space Shuttle reliability]

The use of minimal knowledge in mechanical systems reliability assessment is considered. The design analysis of the US space shuttle solid rocket booster joint is used as an example of this approach and an approximate shell analysis of the joint is presented. Approximate analysis methods, it is argued, are well suited to the breadth-first reliability assessment required early in the design process for failure prevention. Implications of this approach are discussed for other engineering failures and the mechanical design process in general
