Methodology of Evaluating Margins of Safety in Critical Brazed Joints

摘要

This methodology provides a guide consisting of design, testing, and structural analysis steps developed to assure positive strength margins of safety (MS) in critical brazed joints used for assembly of flight and non-flight structures.This effort was promoted by concerns expressed by industry and NASA engineers and program management that the current practices of assuring positive MS in structural brazed joints vary widely among the centers, NASA contractors, and manufacturers, making the verification of structural adequacy difficult in cases involving multiple centers, other government agencies, and their suppliers.
