A hydraulic method for determining incipient yield pressure of thick wall cylinder;

This paper performs the limit analysis of a thick wall cylinder of linear strengthened material based on the unified strength theory.

Using elastic solution of thick wall cylinder, it is analyzed that the optimum design on three-layers assembled cavity die of cold extrusion under the elastic limit stress.

The results show that experiments are accordant with numerical simulation and when the preparatory hole is reverse-conical and its mean diameter is 11 mm,acceptable nozzle sizes can be obtained after hole flanging on thick-wall cylinders.

Influence of the workpiece s pre-hole diameters and passes on thick-wall cylinders hole flanging is investigated by experiment and numerical simulation.
