Fatigue is a failure mechanism caused by repeated cyclic loading that leads to cumulative damage within a material and ultimately catastrophic failure. Between 80% to 90% of all mechanical service failures can be attributed to Fatigue, therefore it is critical to test and characterize the fatigue properties of materials and components. Fatigue failures occur when a material is loaded repeatedly but below the stress level that would cause immediate failure and, in many cases, even below the yield stress of the material. With each loading cycle, damage to the material accumulates
