A second generation finite element computer code was developed with specialized features for accurate evaluation of solid propellant case liner bond regions. The code uses six-term quadratic elements for propellant modeling, special thin liner elements for liner and insulation modeling, and a crack tip element for modeling boots and cracked regions. Mesh generation is automated with variable density spacing and input format is optimized for minimum labor during problem setup. The code contains a rezone feature for selective refining of specific high stress gradient regions and rerunning for maximum accuracy. This new computer code was made available to the solid propellant industry at a computer users course in October 1973. (Modified author abstract).
