R. Ganesh Narayanan, IITG Hot working: Involves deformation above recrystallization temperature, between 0.5T m to 0.75T m. Advantages: (1) significant plastic deformation can be given to the sample, (2) significant change in workpiece shape, (3) lower forces are
For sheets in the deep-drawing process, wrinkling is the one of the most commonly seen defects and can take place in both the side-wall and flange area. In addition, wrinkling may occur in the flange area in sheet spinning, along the feeding direction of a flat strip under extrusion, and in the circumferential direction of an annular thin film under torque.
b=e 2 /e 1. which vary from equal biaxial stretching ( b = 1) to uniaxial compression ( b = -2.) Figure 3 shows the strain paths along two lines in a rectangular pressing. Such diagrams are strain signatures of the part. Unequal biaxial stretching ( b 1) will occur in the middle, A. In the sidewall, C, plane strain is most likely.
If our film sheet is 60 wide and .002 thick, then the cross sectional area: 60 x .002 = 0.12 square inches Therefore the maximum allowable tension would be:
Its 9.8 meters per second squared. If we look at all the units, they actually do turn out with you just ending up having just meters cubed, but lets do the math. We get 8 divided by 1,000 divided by 9.8 is equal to 8.2 times 10 to the negative 4. V equals 8.2

Maziar Ramezani, Zaidi M. Ripin, in Rubber-Pad Forming Processes, 20126.1 Introduction Deep drawing is a common process in industry for manufacturing products from sheet metals. Very complex parts can be achieved using deep drawing. The process is widely used for producing different products such as automotive parts, cans, sinks and housing, and the application
Sheet metal fabrication is a comprehensive cold-working fabrication process for sheet metal (usually less than 6mm), including shearing, blanking, bending, welding, riveting, die forming and surface treatment etc. Its remarkable feature is that the thickness
