Constitutive Model of Stress-strain for 0Cr20Ni12Mn5Mo2NbN Steel under Cyclic Loading

    Graphical Abstract
    • Abstract
  • Cyclic loading tests with variable strain amplitudes were conducted on 0Cr20Ni12Mn5Mo2NbN steel and cyclic stress-strain behavior was analyzed. The results indicated that there was exponent relationship between true stress and true strain. Exponent-strengthen constitutive model for cyclic deformation σ = σ0+ α·eβε was proposed based on the above results.
