Forming Sheet Metals with Hydrostatic Pressure | Metallurgy

In last few years the use of hydrostatic pressure in forming has got greater interest of researchers mainly because of the requirement to manufacture light weight structures for automobiles. Reduction of body weight of an automobile can be achieved by using lighter gage sheets of steel or by using sheets of lighter material like aluminum alloys. In both the cases [...]

Formability of Sheet Metals | Metallurgy

Formability of sheet metal is the ability of sheet metal to be drawn into cups or formed into the desired shapes without any defect. However, in order to have a measure for sake of comparison, the limit drawing ratio (LDR) is taken as a measure of drawability. LDR is defined as below- For most of the sheet materials which are [...]

Forces in Circular Cup Drawing | Metal Formation | Metallurgy

In cup drawing many different processes take place simultaneously. The punch pushes the sheet into the die (Fig. 11.13). The sheet under the punch pulls the remaining sheet in flange under the blank holder plate. As the punch advances, the sheet in flange is pulled over the die profile radius into cup wall. In doing so the sheet in the [...]
