Consider a typical true stress-true strain curve that is approximated by a = K". a) Derive the expression for 'n' at the onset of necking. b) A material has a true stress-true strain curve given by a=689,475.73 kPa. Calculate the true ultimate tensile strength and the engineering UTS of this material.
