РОЗРОБКА МАТЕМАТИЧНОЇ МОДЕЛІ РАДІАЛЬНОГО ТИСКУ ПЛАСТИЧНОГО СЕРЕДОВИЩА ПРИ ОСАДЦІ ПОЛИХ ТІЛ ОБЕРТАННЯ

Abstract

The generalized equalization of equilibrium is got for an axis of symmetry task in cylindrical co-ordinates, the decision of which in an analytical kind allows to define the function of tangent tensions from the co-ordinates of hearth of deformation. The constituents of tensor of tensions are certain for a flat axis of symmetry task. Research of the tense state of the thick-walled pipe at the butt end sinking taking into account radial external and internal head. Influence of radial head is shown on distributing of normal and tangent tensions.
