Paper Abstract

The experimental-theoretical research of the plastic deformations of thin-walled tubular specimens was executed. The results of experience and forecasts of the kinematical hardenings model, multisurface model and one of structural model of a material were compared. The adequacy of models with the complexity of researched processes was established proceeding from sufficient accuracy of forecasting of deformations, stresses, saved and dissipative deformations energies. The researches are executed for complex periodic loading paths, containing partial and complete unloadings.
