For some metal alloy, a true stress of 345 MPa (50,000 psi) produces a plastic true strain of 0.02. How much will a specimen of this material elongate when a true stress of 415 MPa (60,000 psi) is applied if the original length is 500 mm (20 in.)? Assume a value of 0.22 for the strain-hardening exponent, n.

The indentation hardness of a material, H, is often related to the yield strength by H = 3Ꝺy, where Ꝺy is the true yield stress at a nominal plastic strain of 8%. If the true stress - nominal strain curve of a material is given by Ꝺ = Aɛn and n is 0.2, calculate the tensile strength, ꝹTS, of a material for which the indentation hardness is 600 MN/m2. Assume that tensile strength ꝹTS =
