The report documents results of an 18-month study program to develop improved methods for case bond structural analysis. The study was limited to unflawed bond systems in solid propellant rocket motors. In Task I of the program, parametric stress solutions were obtained for cylindrical motor configurations with flapped and right-angle bond terminations. In Task II of the program, improved test sample configurations were developed for the measurement of case bond tensile and shear strength. Based on results obtained from this program, techniques for the assessment of case bond integrity have been placed on a level equivalent to existing techniques for the assessment of grain integrity at the centerport.
