Given the properties in the table below
a. Plot the engineering stress-strain curves for the 3 materials. You can assume the materials behave linearly when they plastically deform.
b. Which material is the strongest?
c. Which material is the stiffest?
d. Which material is the toughest?
e. If you impose a 1% strain what happen to the three materials
f. After removing the 1% strain is there any permanent deformation in any of the materials? If so how much? Will any of the material properties in the table change? If so what is the new property?
