ABSTRACT
This chapter concisely elucidates the underlying mechanism of fatigue process at nanolevel, using MD simulations. Types of cyclic loading patterns involved in fatigue are explained in detail. The parameters of fatigue analysis and their effects are described. The test procedure for fatigue is explicated in a step-by-step manner to simulate the materials. The structural evolutions of the metals have been explained during fatigue loading simulation through OVITO parameters (such as atomic strain, centrosymmetry parameter, common neighbor analysis, and dislocation analysis). The impact of cyclic loading on fatigue behavior is also described using atomic snapshots of the fatigue process at a suitable number of cycles with respect to temperature and strain rate.
