抄録

It is known that a plastic deformation of a tube to be sunk beginns at the portion which does not come to contact with the die wall. This deformation of tubes is analysed under certain hypotheses. As a result, the deformation and the ratio of the stress to be added to cause the deformation to the yield stress of tube materials can be expressed in dimensionless terms determined by the sinking conditions and the properties of the materials. Experiments were made and confirm that the obtained equations are available for sinking dies designing.
