title: APPROXIMATION OF THE FLOW OF A LAYER OF LIMITED THICKNESS OF A MULTI-CONNECTED CONTOUR BY A COLLECTION OF FLOW OF SINGLE-CONNECTED AREAS
abstract: The calculations are based on the one proposed by A.A. Ilyushin. theory of flow in a thin plastic layer, enclosed between two surfaces of tool bodies approaching according to a given law, under the assumption that: the material of the spreading layer is ideally plastic and volumetrically incompressible; elastic deformations of the tool are small and can be neglected; on the contact surfaces of the metal layer with the tool, the classical L. Prandtl flow law is accepted. To study the characterist
