摘要
在本构关系中引入焦曼导数,导出大变形弹塑性本构方程,结合有限单元法,在微观层次上对金属晶体材料的变形进行了计算,与以往的计算方法相比,计算结果更精确.
Introducing Jaumann derivative into constitutive relation, the elstic-plastic largre deformation constitutive equation is obtained, the deformation of metal crystal materials in micro-level is calculated and the results show that the method introduced is more accurate than that gotten by other method.
