EXPERIMENTAL STUDY ON FATIGUE LIFE OF THICK-WALL CYLINDER WITH INNER SURFACE CRACK SUBJECTED TO SUPER HIGH PRESSURE

摘要：

A model used to analyze the fatigue life of thick-wall simulation tubes was set up in this paper and experiments on measuring fatigue life of thick-wall cylinders with inner surface crack subjected to super high pressure were carried out.The results show that the fatigue life of simulation tubers analyzed by this paper’s fatigue crack growth rate achieved through striation delineating and hydraulic pressure cyclic experiment agreed well with the practical results of hydraulic pressure cyclic experiment. With the method of this paper, quantitative problem that has ever been existing in the analysis of fatigue life of thick-wall cylinder can be resolved.
