WebApr 13, 2024 · In the first step, the simulation for static loading is performed using XFEM, and then, in the second step, direct cyclic load (using low-cycle fatigue) is applied on an identical crack and results in both the cases are superpositioned to get the combined effect on the same crack. Table 1 Chemical composition of the used stainless steel (wt%). WebCyclic load and impact load are types of dynamic loads. In case of static loading, load is gradually applied and remains stable after reaching the maximum value giving a steady value of stress. But there are a number of machine members which are subjected to cyclic loads resulting in variable stresses that fluctuate between different levels. prediction roulette free
