We describe physical relationships used for the analysis of stresses and strains in modeling the process of compaction of materials of the vegetable origin with properties of plasticity. The study is based on the yield condition formulated by Green. The analysis uses the basic functions of porosity and the Amontons–Coulomb and Prandtl laws of friction for porous materials. The experimental and theoretical tests of fodder mixture compression are performed in a closed chamber. The identification of material constants is performed by using numerical methods and nonlinear regression equations describing the pressure on the stamps of the chamber.
