I am trying to manipulate some data that were obtained from a three point load experiment on a porcine tibia.
I would like to obtain a stress-strain curve for the various specimens; however, the only data that was given from the Instron three-point loading set up was Load (N) vs Deformation/Extension (mm).
My question is: how do you convert the Load vs Deformation curve to a Stress-Strain curve?
