Redesign of NASA's Solid Rocket Booster

JAR performed a detailed three dimensional finite element analysis of the aft fixed nozzle housing joint of the space shuttle solid rocket motor for Morton Thiokol, Inc. as part of the total redesign effort undertaken after the Challenger accident.

The analysis included bolt preloads and contact between the various components, and was designed to study movement of the O-ring grooves in the joint under loads simulating maximum thrust pressure.
