# Homework #13

1. Given $$E = 10\text{ MPa}$$ and $$\nu = 0.5$$, Create a graph with three separate curves (lines, in fact) of max principal stress versus max principal strain for three cases: (i) uniaxial tension, (ii) plane strain tension (shear), (iii) and equibiaxial tension.

Plot the graphs for strains up to $$\epsilon = 0.10$$, (that's 10%). Don't worry about finite strain effects, or which definitions of stress and strain to use in this case. Use the following page for definitions of the three cases: specialstraintopics.html.

2. Plot the max principal engineering stress versus max principal engineering strain, up to $$\epsilon_\text{max} = 0.50$$, for uniaxial tension, shear, and equibiaxial tension, for a material having ($$C_{10} = 0.4$$ and $$C_{01} = 0.04$$ ).

Yes, this question is basically the same as #1 above, but with Mooney-Rivlin terms instead.

That's all.
