Structural behavior of solid rocket motor field jointsStructural analysis studies conducted on three concepts for the Space Shuttle Solid Rocket Motor field joints are summarized. Deflections and stresses in the Challenger clevis-tang joint are compared with a proposed capture-tang replacement joint and with an alternate bolted joint design. Results indicate deflections and stresses are subsequently reduced in both the capture-tang and bolted joint concepts. The capture-tang and bolted joint designs are respectively 24 and 70 percent heavier than the baseline clevis-tang joint.
