Question
An annealed AISI 1018 steel specimen has a tensile modulus of 210 GPa, a strength coefficient of 620 MPa and a strain-hardening exponent of 0.25
An annealed AISI 1018 steel specimen has a tensile modulus of 210 GPa, a strength coefficient of 620 MPa and a strain-hardening exponent of 0.25 (assuming a power-law relationship ????̃=????????̃ ???????? for σ>σy). What permanent deformation must be applied to increase the 0.2% offset yield strength by 40%?
