- Why the cupping test may not predict well the formability of sheet metals in actual forming processes? Cupping test uses square or rectangular specimens only. Strain in some forming operations is not axi-symmetric. Cupping test is mainly for compression Stress is rarely uni-directional in sheet metal forming.arrow_forwardBased on the following specification (Figure: 12), state whether the measured component would be accepted or rejected. Please give the reasons for your decision.arrow_forwardWhat is tensile testing?arrow_forward
- 1) What is the shear modulus and how can it be obtained from a torsion test? 2) Explain why it is necessary to consider geometric factors when determining distortion in torsional testing.arrow_forwardTwo previously undeformed specimens of the same metal are to be plastically deformed by reducing their cross-sectional areas. One has a circular cross section, and the other is rectangular; during deformation the circular cross section is to remain circular, and the rectangular is to remain as such.

- Questions: 1. Two thick slabs of 300mm each, the first one is used in cold rolling where u=0.08 while the second is used in cold rolling where u-0.5. The mill roll diameter in each case is the same as 600mm. Determine the max draft (reduction) in both cases. Discuss the wide difference in results. = 2. A tensile specimen of the metal of 100 mm is length stretched to a length 157 mm during the rolling process. If the metal has a flow curve with parameters: K = 850 MPa and strain hardening exponent n = 0.30. Determine the average flow stress that the metal has been subjected to during the deformation.arrow_forwardHardness tests are performed more frequently than any other mechanical test for several reasons: (Choose all that apply): Other mechanical properties can be estimated from hardness data such as tensile strength The test is simple and inexpensive The test is nondestructive, which means that the specimen is neither fractured or excessively deformed after the test Testing apparatus is relatively expensivearrow_forward10. Two previously undeformed specimens of the same metal are to be plastically deformed by reducing their cross-sectional areas. One has a circular cross section, and the other is rectangular; during deformation the circular cross section is to remain circular, and the rectangular is to remain as such.

What are the limitations for distance from specimen edge to indentation and distance between indentations? Explain why these limitations exist in both cases.arrow_forwardBriefly discuss the differences between the Engineering Stress versus Engineering Strain and the True Stress versus True Strain Diagrams for the test specimen. Briefly explain why the two plots are different. When is the use of Engineering Stress versus Engineering Strain invalid?arrow_forward
