Rotating Beam Fatigue and Axial Fatigue Test Methods. The main difference between the two test methods is that axial fatigue testing applies uniform stress throughout the cross-section of the specimen under test, whereas rotating beam fatigue testing creates an applied stress that increases linearly from 0 at the neutral axis to a maximum stress value at the specimen surface.
