1) material failure
材料失效
1.
Combining with the material failure rule, shear failure and element deletion in ABAQUS, this study has realized the separation of the chip in cutting process from the work-piece and obtained correlated change tendency of stress, strain and the cutting force in the cutting process, which is conformed to the cutting theory.
运用ABAQUS有限元分析软件对二维切削加工过程中非线性、弹塑性进行了有限元分析,结合ABAQUS中材料失效准则、剪切失效、单元删除等实现了切削过程中切屑的分离,同时得出了切削过程中应力、应变、切削力的变化趋势,符合一般切削理论。
