AN INVESTIGATION OF THE ROTATING-BEAM TEST FOR LOW-CYCLE FATIGUE CRACK PROPAGATION STUDIES,

Abstract

A method is described for investigating the lowcycle fatigue behavior of high-strength, notchtough materials using standard rotating beam fatigue machines. The method includes the application of tensile tests on partially fatigued specimens to obtain notch tensilestrength and crack depth information. An analysis based on experimental data from HY-80 steel specimens of three sizes and three heattreatments is presented. Crack depth and crack propagation rate are employed as parameters in the analysis. (Author)
