Calculate the areas under the stress-strain curve (toughness) for the materials shown in Fig. below, (a) plot them as a function of temperature, and describe your observations. (b) As expected, the elastic modulus of the polymer decreases as
temperature increases. Using the stress-strain curves in the figure, make a plot of the modulus of elasticity versus the
temperature. Comment on the shape of the curve.
