Abstract：
|
|
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.
