Module $8$ Lab$-$ Mechanical Testing and Plastic Deformation

$2.$ The following engineering stress$-$strain data points were obtained for a $0\mathrm{.}20\%C$ plain$-$carbon steel:

$\backslash$table$[[\backslash$table$[[$Stress$],[($MPa$)]],0,207,379,414,469,496,510,524,517,503,476,448,386,352],[\backslash$table$[[$Strain$],[(\%$EL$)]],0,0\mathrm{.}1,0\mathrm{.}2,0\mathrm{.}5,1\mathrm{.}0,2\mathrm{.}0,4\mathrm{.}0,6\mathrm{.}0,8\mathrm{.}0,10\mathrm{.}0,12\mathrm{.}0,14\mathrm{.}0,16\mathrm{.}0,\backslash$table$[[19],[$Fracture$]]]]$

a$.$ Plot the stress strain curve.

b$.$ Determine the ultimate tensile strength of the alloy

c$.$ Calculate the elastic modulus of the alloy

d$.$ Determine the $0\mathrm{.}2\%$ offset yield stress of the alloy

e$.$ Determine the percent elongation $(\%$EL$)$ at fracture

f$.$ What kind of behavior is demonstrated $-$ ductile or brittle?
