The analysis and modeling of processes of drawing of axisymmetric products. Deals with physical and mechanical aspects and criteria plastic power-demote. When drawing with wall thinning there is no noticeable change in diameter of the workpiece. Therefore, the defor-mation of an axisymmetric shell in the circumferential direction is small compared to the linear strain change in the length and thickness of the shell. This circumstance allows to make when the hood with thinning the plane strain condition.
