ME 382 Fall 2010 HW1 Solutions Page 7 Below is a true stress versus true strain curve from an ME395 lab, in which a tensile test is conducted on an annealed sample of brass. The modulus of brass is 105 GPa. Calculate the slope of the elastic unloading curve in an engineering (nominal) stress-strain curve for the annealed brass below at a nominal strain of (a) 2% and at a nominal strain of (b) 25%. What would the slopes of the unloading
