Paper Abstract

Experimental - theoretical research of the plastic deformation of thin-walled steel and nickel tubular specimens was done. The experimental results and forecasts of the kinematical hardening model and multisurface model with one active surface were compared. A modification of the plasticity theory was gone. The modification takes into account character of a loading path. The constitutive equation gives the possibility to make predictive calculations when either loading or strain path (in whole strains) is known. The research is performed for complex periodic loading paths, containing partial and complete unloading.
