dc.description.abstract	Abstract. In this article, in terms of the first and second laws of thermodynamics, as well as the principle of maximum energy dissipation rate, a continuum elastic-plastic theory for porous materials is proposed. Unlike the Prandtl-Reuss equation, the influence of plastic volumetric strain is fully taken into account. An incremental elastic-plastic constitutive law is derived, and a series of yield criteria is proposed. Its implementation is demonstrated with a simple example. This study offers a new perspective for modeling the elastic-plastic deformation of porous materials.
