Abstract: Within a method of small parametre the field of stresses of heavy tubing cylindrical pipes is investigated at modelling of a material by the incompressible elastic-is viscous-plastic environment. The estimation of influence on size of a plastic zone physicomechanical design parametres is given.

Key words: plane deformation, tensor of deformation, elasticity, plasticity, elastoplastic line, elastic-is viscous-plasticity.
