摘要：

By the introduction of a new set of coordinates for the normal stresses a framework is developed which facilitates the implementation and modification of a variety of yield surfaces. An internal variable is proposed which allows the simultaneous description of two strain hardening paths, one in tension, the other in compression. Finally, the numerical aspects of the problem are presented.
