A tension test was performed on a specimen having an original diameter of 12.5 mm and a gage length of 50mm.
The data are listed in the table below:
Complete the following:
Plot the stress-strain curve. Label the y-axis every 50 MPa, and the x-axis every 0.05 mm/mm.
Plot the linear portion of the stress-strain curve (first 5 points). Label the y-axis every 50 MPa, and the x-axis every 0.001 mm/mm.
Determine the approximate Modulus of Elasticity
Determine the approximate Ultimate Stress
Determine the approximate Fracture Stress
Determine the approximate Modulus of Resilience
Determine the approximate Modulus of Toughness
Other Requirements:
Provide an example hand-written calculation showing how you calculated one point on the curve.
Remember to properly label your plots and provide axis labels with units.
Hand sketched plots will not be accepted. Use Excel or similar software.
Tensile test specimens are extracted from the "X" and "y" directions of a rolled sheet of metal. "x" is the rolling direction, "y" is
transverse to the rolling direction, and "z" is in the thickness direction. Both specimens were pulled to a longitudinal strain =
0.15 strain. For the sample in the x-direction, the width strain was measured to be ew= -0.0923 at that instant. For the sample in
the y-direction, the width strain was measured to be gw=-0.1000 at that instant.
The yield strength of the x-direction specimen was 50 kpsi and the yield strength of the y-direction specimen was 52 kpsi.
Determine the strain ratio for the x direction tensile test specimen. Determine the strain ratio for the y-direction tensile test
specimen. Determine the expected yield strength in the z-direction. Give your answer in units of kpsi (just the number). If the
sheet is plastically deformed in equal biaxial tension (a, = 0, to the point where & = 0.15, calculate the strain, 6, that would be
expected.
(Suppose you need to design a tension test machine capable of testing specimens that have nominal ultimate stresses as high as σu = 100 ksi . How much force must the machine be capable of generating? Assume the testing specimen has the ASTM shape shown. Answer for this is 19.6 kip)
(If the maximum nominal strain is ϵf = 0.7 just before the test specimen fractures and the test machine operates by moving only one grip, how far must that grip be designed to travel? The total length of the deforming part of the specimen is 3 in. Answer for this is 2.10 in)

- A strain rosette was attached to the outer surface of stainless vessel when the vessel is in a stress-free state. The vessel was then put under a complex loading (pressure, bending and torsion) state. The train readings for the three strain gage elements in the strain rosette were recorded as: Ea=210, Eb=160, Ec-330, all in micro-strains.
