根据一种组合强化模型及其弹塑性有限元计算程序，依据有关实测结构，通过等向强化和Ｚｉｅｇｌｅｒ随动强化的适当组合，满意地计算了两种铝合金板材不同胀孔量下的冷胀残余应力，获得了组合比例与胀孔量的关系。同时进行了二次胀孔及干涉配合与拉伸大载荷相互作用的算例计算和分析 According to a combined strengthening model and its elastoplastic finite element program, based on the measured structure, the appropriate combinations of isotropic strengthening and Ziegler follow-up strengthening were used to satisfactorily calculate the cold expansion at two different kinds of aluminum alloy plates Residual stress, get the combination ratio and the amount of bulging hole. At the same time, the calculation and analysis of an example of the interaction between secondary bulge and interference and tensile large load
