Determination of Hoop Stresses Induced in a Cylindrical Steel Die by Compacting Metal
Because of the lack of stress data, steel dies for compacting metal powders were designed in the past on the assumption of hydraulic pressure transmission by powders. True die stresses existing in a hardened steel die during the compacting of various lubricated and non-lubricated powders have been measured by mounting strain-gauges on the periphery of the die at numerous points along its length. Values of the hoop stress varied from approximately 0·05 to 0·40 of the calculated and measured hydraulic fluid stress. Finally, for a particular metal powder, the stress was a function of the average particle size, the powder height, and the amount of lubrication.
