| 摘 要： | 借助有限元软件ABAQUS前处理功能建立铝板的几何模型,构建了纯铝单晶模型的用户材料子程序,并将其嵌入到ABAQUS有限元程序中,实现对铝板弯曲过程的模拟。该模拟过程分析了在采用单晶体塑性本构理论不同压下程度的铝板弯曲情况,得出在采用单晶模型理论时能够很好的反映出材料变化的不均匀性,以及压下程度的不同对滑移系启动的影响。

| Abstract: | With the aid of finite element software ABAQUS pretreatment functional aluminum plate geometric model is set up, To build the model of pure aluminum single crystal user material subroutine, And embedded into the ABAQUS finite element program, Implementation of aluminum plate bending process simulation. Adopted in the simulation analysis of the single crystal plasticity constitutive theory level of aluminum plate bending under different pressure conditions,Obtained when using single crystal model theory can well reflect the inhomogeneity of material change,And the different pressure effect on the slip system startup. |
