- What is the difference between plate and sheet material?arrow_forwardBoth extrusion and bar drawing processes can be used to reduce the cross section. What can be the basic differences between extrusion and bar drawing processes?

- How can the direction of shear flow be established?arrow_forwardThe figure below shows a symmetric plane-strain upsetting process. The process may also be thought of as a form of side extrusion. Observations show that the deformation is confined to two shear planes, each one being analogous to that seen in plane-strain cutting. You may assume that there is no friction between the work material and the tool/die walls; the uniaxial yield strength of the material is σy and is independent of strain rate and temperature, and the material behaves as a rigid plastic solid. a) Calculate the pressure (p) required for the upsetting process in terms of σy. b) If friction existed at the die walls and the frictional work (energy) dissipation was 30% of the energy required for shape change alone (part (a) above), then what would be the pressure (p)?arrow_forwardIn a blanking operation to produce steel washer, the maximum punch load used is 3 x 105 N. The plate thickness is 5 mm and percentage penetration is 25. What is the work done during this shearing operation?arrow_forward
- 3) Which of the below statements is/are correct regarding deep drawing process? i. If the clearance between the punch and the die is less than the thickness produced by free thickening, the metal in these regions will be squeezed, or ironed. ii. The force on the punch required to produce a cup is the summation of the ideal force of deformation, the frictional forces, and the force required to produce ironing (if present). i only ii only Both i and ii None of the abovearrow_forwardName the four basic bulk deformation processes.arrow_forwardWhich of the following is true about open die forging process? O Forged pieces have accurate dimensions therefore there is usually no need for additional finishing operations such as heat treatment or machining. O Forged pieces have outstanding grain structure and the best combination of mechanical properties. O Forging is carried out at temperature above re-crystallization temperature Forged pieces are small in size since the forging process is incapable of doing large components such as turbine shafts.arrow_forward
