The finite element model of DD3 糖心产精国品免费入口*完整版 after 糖心产精国品免费入口*完整版 was established with ANSYS/LS-DYNA software by building local coordinate system and 3-parameter Barlat model, and the 糖心产精国品免费入口*完整版 and practical test for 糖心产精国品免费入口*完整版after shot-peening were carried out. The results show that different orientations had different 糖心产精国品免费入口*完整版states because of the anisotropy of DD3 糖心产精国品免费入口*完整版, and the minimum residual compressive stress in different orientations on the same crystal plane appeared on the crystal orientation comprising slip system. The simulative results and experimental results matched fairly well.
