A tensile test was conducted on a specimen that had an original diameter of 0.5 in. It fractured with an applied load of 71100lb. Determine the true stress and true strain at fracture if measured diameter of the fracture part was 0.3in.
I believe for fracture, true stress and strain are:
True strain = ln(original area/final area)
True stress = applied load/final area
However, Im not quite sure
