(2) to examine the second floor of the outer ring set squeeze tube along the radial hoop stress and then decreased, and the radial stress first decreased and then rose pattern. In addition, from the height z direction can be obtained from the stress analysis of sets of circular extrusion container, as the multi-reference: the conclusion of plane stress problems. (3) pointed out that the three sets of extrusion cylinder and the outer layer comprising a circumferential and radial stresses similarity, noting that the three sets of Extrusion die wall at the equivalent stress and circumferential stress increased,[link widoczny dla zalogowanych], die can be greatly reduced in the working conditions circumferential tensile stress, which illustrates the simple use of multi-sets of extrusion to improve the reliability of its strength.
