EVALUATION OF THE EFFECT OF TECHNOLOGICAL PARAMETERS ON THE SIZE OF THE NONDEFORMABLE ZONE WHEN PRESSING A POROUS WORKPIECE IN A CONTAINER

摘要

The solution of the variational problem of pressing a compressible medium in a closed container made it possible to determine the relation between the sizes of the nondeformable and plastic zones. It was confirmed that the friction and lateral pressure coefficients have a substantial effect on the size of the nondeformable zone.
