抄録

In this work, a proto-type high-pressure fatigue testing machine capable of generating high internal pressure and high frequency up to 15Hz with high efficiency was constructed first, and then it was used to carry out a repeated internal pressure test for A2017-T4 cylindrical specimens. It was found through Weibull statistics that there are three peaks in the time-strength distribution and each peak is closely connected with the fractographical feature. A new estimating method of fatigue limit using Weibull's location parameter was suggested.
