摘要：
A mathematical model is developed to calculate the geometric, kinematic, force, and energy parameters and to determine the change of density during the rolling of initially porous square bars and octagon semiproducts. The model is based on a basic energy equation and a variational equation derived from the principle of the minimum total deformation energy. The model is used to analyze the effect of the percent reduction, the friction coefficient, the roll radius, and the temperature on the geometry, the kinematics, and the energy-force parameters of the process.
