Abstract:

The fatigue life characteristics of the 175mm M113 gun tube, which was fabricated with 170-190 ksi yield strength material, have presented problems of considerable concern. The advantages to be gained by use of a lower strength material and autofrettage, shown by prior fatigue life investigation of pressurized thick wall tubes, are confirmed in respect to this tube in this investigation.
