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.

During a forming operation, the final true strain that the metal experiences ε = 0.73.Determine the flow stress at this strain and the average flow stress that the metal experiencedduring the operation.

Draw a stress Mohr circle for each test (let the specimen axis, i.e. longitudinal direction, be x-axis and the transverse direction be y-axis) and express both the maximum principal stress (σmax) and the maximum shear stress (τmax) in terms of σ (for tension test) or τ (for torsion test).

- Nonearrow_forwardplease includde scetcharrow_forwardDetermine the resulting maximum value of the normal stress. Specify the orientation of the plane on which these maximum values occur. **The answer is tensile stress is 0 ksi at 90 degrees. **The answer is compressive stress is 7 ksi at 0 degrees. Can you explain how that is? This was my thought process: I know that tensile would be zero because the force P is actually going inwards and not outwards. I know that means that there would be a compressive force. I am confused on the angles, how is a tensile force going 90 degress if there technically is no force in the tensile direction. And how is there a compressive force at 90 degrees if there is a stress? thank you!arrow_forward
