Abstract

This paper is devoted to study the non-associated constitutive law of soil materials and to construct a bi-potential for the classical Drucker-Prager (D-P) plastic model. It can be proved that the bi-potential not only satisfies the constitutive relationship of the D-P model, but also conforms to the non-associated flow rule. We present the relevant algorithms for the integration of soil constitutive equations. Two simple numerical examples illustrate the rationality of the bi-potential theory and the feasibility of its algorithm.
