Prediction of Life on High Temperature & Low Cycle Fatigue for 3-Dimension Structure

Abstract:

The high temperature & low cycle fatigue were experimentally studied with the 3-dimension notched 2.25Cr—1Mo steel specimens. The 3-dimension stress-strain responses of specimens were calculated by means of the program ADINA. The prediction method of 3-dimension fatigue life was discussed according to the theory of high temperature strength. The results of experiments and calculations showed that the equivalent strain range can be served as the valid mechanics for predicting fatigue life.
