摘要
按Mises屈服准则求解板料成形问题, 理论严密, 结果准确。本文提出了一种Mises准则的圆形屈服轨迹图。利用这种圆形屈服轨迹图求解轴对称板料成形问题, 可使求解过程简化, 使求解结果更加清晰、直观。与传统的椭圆屈服轨迹比较, 有明显的改进。
The solving method of the axisymmetric sheet forming by use of Mises yield criterion,is close theoretically and the solution is exact.In this paper,a diagram of circular locus of Mises yield criterion is introduced.Making use of this diagram,the solving process is simplified and the result is visual and clear.As compared with the diagram of elliptical locus of Mises yield criterion,the diagram of circular yield locus is more available for use.
