Rotating Bending Fatigue Test
The rotary bending fatigue test evaluates the fatigue behavior of materials under cyclic bending stress. A rotating specimen is subjected to a constant bending moment, generating alternating tensile and compressive stresses. The test is used to determine fatigue life, endurance limit, and S–N curves, and is widely applied for durability assessment and design validation of rotating components such as shafts, axles, springs, and transmission parts.
