EFFICIENT FATIGUE SIMULATION USING PERIODIC HOMOGENIZATION WITH MULTIPLE TIME SCALES
要約
A periodic time homogenization method is presented to efficiently simulate material fatigue. By separating several time scales, a time transient evolution model is solved at a slow time scale only, by taking into account the averaged effect of the high-frequency cycles in the homogenized solution. A significant computational gain can then be obtained when compared with a direct simulation of the reference problem.
