Abstract: A method for assessing fatigue damage and a fatigue life based on a crystal plastic welding process model. According to the new method, consideration is given to the effects of the crystal slip system and the polycrystal plastic strain on the welding process performance of the material. A welding process damage and fatigue life assessment model is established on the mesoscopic scale. The effect of microscopic characterizations of materials on the welding process performance, as well as on the fatigue damage and life of welded joints, can be studied from the mesoscopic point of view. The relationship between the welding process and the evolution of the material performance can be determined by the macro-mesoscopic coupling calculation model to further determine the effect and degree of welding processes on the fatigue damage and life of materials.
