TLDR
In this article, the authors present the results of experiments concerning the motion of the yield and the loading surfaces and the interrelation between these two motions, and show that the yield surface tends to become tangent to the loading surface, and that the plastic strain vector is normal to yield surface.Abstract:

On the description of anisotropic workhardening
TL;DR: In this paper, a model of workhardening is proposed which generalizes the known rules of isotropic and kinematic work-hardening by introducing the concept of a "Field of Workhardening moduli".

A model of nonlinearly hardening materials for complex loading
Yannis F. Dafalias,Egor P. Popov +1 more
TL;DR: In this article, the authors introduced the concept of a bounding surface in the stress space which always encloses the loading surface, and a parameter defined by the relative position of the loading and the bounding surfaces, and the plastic work done during the most recent loading, determine the value of the plastic modulus.
