Homework Statement
I was creating a stressstrain curve for a soft aluminum alloy (as stated in problem) and was looking to find the ultimate stress and ensure my units were all okay.
I have attached a screenshot of my graph. And a separate screenshot with the formulas.
Homework Equations
E=σ/ε
σ=P/A
ε=δ/L_{0}
The Attempt at a Solution
I think I have my graphs correct. I am aware of how to get the modulus of elasticity, yield strength, but the ultimate strength is confusing me on this one. It couldn't be the strength at fracture. How can I find it?
Also, if anyone could confirm that my units are set up correctly, I would greatly appreciate it.
