... and torsional fatigue behavior of severely notched components made of additively manufactured 17-4 PH stainless steel was studied in the present paper. The experimental fatigue tests were performed under axial- and torsional-loading conditions. Cylindrical specimens with notch tip radius of 0.1 mm were employed...

... Cumulative fatigue behavior of a wrought cobalt-base superalloy, Haynes 188, was investigated at 538°C under various single-step sequences of axial and torsional loading conditions. Initially, fully-reversed, axial and torsional fatigue tests were conducted under strain control at 538°C on thin...

... Constant amplitude torsional fatigue tests have been performed on smooth specimens of quenched and tempered steel at two strength levels. Both unidirectional and fully reversed tests have been performed. It was found that there was no detectable effect of mean strain upon fatigue life of either...

... This paper presents the results of a study to develop a methodology for predicting torsional fatigue damage to a turbine-generator rotor subjected to transient electrical disturbances. This methodology used torsional properties obtained from constant amplitude tests on 25.4-mm-diameter specimens...

... containing voids failed at lower shear stresses and less catastrophically. In torsional fatigue, all failures occurred by the propagation of resin-bound shear cracks at shear stresses below the static strength of the material. The dynamic (vibration) test parameters showed permanent and progressive changes...
