摘要: 本文讨论了屈服函数在π平面上外凸的条件,并提出了一个能保持曲面外凸且无棱角的屈服函数,这个函数比德鲁克-普拉格(Drucker-Prager)屈服函数更接近于摩尔-库伦(Mohr-Coulomb)屈服函数,因而在一定程度上具备了这两个屈服函数的优点而避免了它们的缺点。

Abstract: In this paper the convex condition of the yield function in π-plane is discussed. A new yield function which has no corner in π-plane, and can always keep convex is proposed. It is more approximate to Mohr-Coulomb yield function than Drucker -Prager yield function. Hence this yield function has some advantages of the above yield functions and can avoid their disadvantages.
