Question

A round steel bar with a diameter of 12mm and a gauge length of 0.5 mm was subjected to tension to rupture following ASTM E-8 test procedure. The load and deformation data were as shown in Table. Using a spreadsheet program obtain the following:

  1. A plot of the stress–strain relationship. Label the axes and show units.
  2. A plot of the linear portion of the stress–strain relationship. Determine modulus of elasticity using the best fit approach.
  3. Proportional limit.
  4. Yield stress.
  5. Ultimate strength.
  6. When the applied load was 18kN, the diameter was measured as12.7mm Determine Poisson’s ratio.
  7. After the rod was broken, the two parts were put together and the diameter at the neck was measured as 10.6 mm. What is the true stress value at fracture? Is the true stress at fracture larger or smaller than the engineering stress at fracture? Why?
  8. Do you expect the true strain at fracture to be larger or smaller than the engineering strain at fracture? Why?
