Please match the following to the appropriate areas or sublocations illustrated on the steel stress-strain curve shown below:
(ultimate tensile stress- yield stress - repture stress)
(4) The maximum stress point on the stress strain curve.
(2) The point where the proportional limit ends and the moment the elastic limit of the specimen is reached, the specimen will return to its original state after the loading is removed. Typically occurs before the steel specimen starts to plastically yield.
(5) The point at which the steel specimens has underwent necking and breaks. This typically occurs after the maximum stress is reached during the experiment.
2. A metal alloy has been tested in a tensile test with the following results for the flow curve
parameters: strength coefficient = 620.5 MPa and strain-hardening exponent 0.26. The
same metal is now tested in a compression test in which the starting height of the specimen
= 62.5 mm and its diameter = 25 mm. Assuming that the cross section increases uniformly,
determine the load required to compress the specimen to a height of (a) 50 mm and (b) 37.5
mm.
3. The starting length of a shaft is 25.00 mm. This shaft is to be inserted into a hole in an
expansion fit assembly operation. To be readily inserted, the shaft must be reduced in length
by cooling. Determine the temperature to which the shaft must be reduced from room
temperature (20° C) in order to reduce its length to 24.98 mm. Refer to the Table below.

- Question 4 Save Answer You do a series of tensile tests on plates of a magnesium alloy that have been subjected to prior cold rolling to true plastic strains of 0.1, 0.2 and 0.3. The resulting true stress-true strain curves are shown below (including a zoomed in version expanding on the small strain region). It is reasonable to approximate the the 0.2% offset yield strength of the magnesium as ✓ MPa for 0.2 and ✓ MPa for 0.3. Assuming the yield strength is ✓ MPa for 0.1 plastic strain, proportional to the square root of the prior true plastic strain results in a hardening coefficient of approximately k= MPa. Hence, we can predict that we need a prior plastic strain of approximately True Stress (MPa) True Stress (MPa) True Stress (MPa) 250 200 150 100 50 0 0.00 250 200 150 100 50 0 0.00 250 200 150 100 50 0 0.00 Ep = 0.1 0.01 Ep=0.2 0.01 Ep=0.3 0.01 0.02 True Strain 0.02 0.03 0.02 0.03 True Strain 0.03 0.04 0.04 0.04 True Stress (MPa) 0.05 0.000 0.001 True Stress (MPa) Ep=0.1 True…arrow_forwardThe force required to punch a 25 mm hole in mild steel plate 10 mm thick, when ultimate shear stress of the plate is 500 N/mm2 will be nearlyarrow_forwardA specimen with a length of 50 mm, width of 20 mm and thickness of 5 mm is subjected to a tensile test and the results obtained are given below.
