I NTRODUCTION racks and damage in structural components arise from various factors including mechanical loading, thermal stresses, environmental conditions, and material defects. Mechanical loading, such as cyclic or impact loading, often initiates micro-cracks that can propagate over time due to fatigue, leading to significant structural damage [1]. Fatigue crack initiation results from cyclic slip and plastic deformation, primarily through dislocation activities. These C
