Abstract:

Stress intensity factors are determined for internally and externally cracked, pressurized thick cylinders with partial autofrettage less than 100 overstrain. The solutions are based on a superposition of existing solutions which does not involve any loss of accuracy. Implications of the stress intensity factor results for the safe-life design of gun tubes are discussed. Various suggestions for future work are presented. Author
