Homework Statement
Establish the constitutive relationship for the cantilever beam material, i.e., provide an empirical formula for the relationship σxx=σxx(εxx) and generate a plot of this relationship. What is the cantilever beam material?
Homework Equations
This is a pure beam bending theory lab, rosette gauge on beam with loads and displacements from a precision micrometer.
The Attempt at a Solution
Not really sure what this question is asking. Also I'm confused about the equation. Wouldn't the stress xx just cancel out and εxx=1?? I got a bunch of data on the beam from the rosette gauge, but I don't really get this question. Any help on shedding what its asking would be great. thanks.
