De Saxcé [G. De Saxcé and Z.-Q. Feng, Math. Comput. Modelling 28, No. 4–8, 225–245 (1998; Zbl 1126.74341)] proposed a new formulation of the constitutive law of materials based on the concept of bipotential. This concept is able to describe non-associated laws and to suggest robust numerical algorithms. Materials that admit a bipotential to model their behaviour constitute the class of implicit standard materials. This class contains, as a sub-class, the generalized standard materials.
The authors introduce the notion of Hill’s bipotential, which is a bipotential expressing the coaxiality of two tensors with preservation of the order of the eigenvalues.
