Metal Fatigue
Metal Fatigue Metallic fatigue occurred at both low and high temperature. It is considered mainly from the perspective of the interaction between the microstructure, the deformation mode, and the mechanical state (Pineau, et al., 2016). The fatigue strength of metals is depending on the crack growth resistance provided by the grain boundaries, the phase boundaries, and various dislocations present in the material (Vallellano, et al., 2009). Therefore, fatigue crack initiation position and the minimum load cycle number before initiation of fatigue are essential to determine in the fatigue analysis. (Topaç, et al., 2009). Fatigue is a type of failure that takes place in the structures when exposed to dynamic forces. Those dynamic forces will produce dynamic stresses and give rise to fatigue failure of structures. The real-life example is fatigue failure of vehicle’s axle housing arisen due to dynamic stresses that induce by rough and uneven road surface (Topaç, et al., 2009). Ne...
