II. COMPUTATIONAL DETAILS MEF90 (Multi scale Elastic-Plastic Fracture) is a simulation software that is widely used to analyze the fracture and fatigue behavior of materials and structures. It is based on a multi scale approach, which means that it can simulate the behavior of materials and structures at different length scales, from the atomic scale to the macro-scale. This makes MEF90 particularly useful for studying the behavior of materials under complex loading conditions, such as those involving cyclic loading or high temperatures, which are commonly encountered in real-world applications. The small green nodes represent the defects placed equidistant from each other, with the blue nodes representing the pre-deflected crack
