Abstract
The analysis of forming thin ring plates in case of the big plastic deformations taking into account the interconnected change of material thickness and deformation hardening is carried out. It is established, that in case of isotropic hardening the equations characteristing plastic flat intense condition, are displayed on π -planes of the plasticity cylinder in the form of proportional dependence between speeds of radial pressure change and equivalent deformation. Analytical dependences for distribution of the main pressure and deformations are obtained at biaxial homonymic and heteronymic strained conditions for ideally stiff-plastic and hardening models of the deformable material.
