The Comparison of the Three Yedlding Criterion on the Twin T^2、the Twin τ~2 and the Mises

本文通过对双T^2、双τ~2与Mises三种屈服准则的比较，找出三者的差异，证明了双T^2和双τ~2分别是Mises准则的下界和上界。

The paper discussed the comparison among the three plastic yield criterion on the twin T^2, the twin τ~2 and the Mises, found the differences among the three. And proved the lower limit and the upper limit that the twin T^2 and the twin τ~2 respectively are the mises.
