Exercise 10

A student conducted an experiment to determine the behavior of poly(ethy- lene) and poly(tetrafluoroethylene) to stress. The tables here depict the results of his experiments.
a. Plot the stress-strain curves for both types of material. Calculate their respective Young's moduli. How do they compare?
b. From their respective plots, determine their approximate strain energy before plastic deformation begins. How do they compare?
c. What do these calculations of Young's modulus and strain energy tell us about the properties of both materials? Compare the properties of both materials using these calculations.
