For a given alloy, the condition for necking dσ = σ is met at a true stress of
dε 350 MPa (50.7 ksi) and a true strain of 0.50.
(a) Determine the corresponding values for the ultimate tensile strength and the engineering strain at necking.
(b) What is the work per unit of volume required to strain this alloy to the point of necking, assuming that σ = kεn?
