| Abstract: |
| The numerical iterative algorithm of the superposed Armstrong-Frederick nonlinear kinematic hardening model under cyclic loadings was investigated based on the Mises yielding criterion and the orthogonal flow rule.The increment of plastic strain was used to attain the equilibrium and convergence of governing equations.To verify the validity of the proposed iterative algorithm,Chaboche and Ohno-Abdel-Karim kinematic hardening models were calculated based on the iterative algorithm,and the analyzed results were in good agreement with those of obtained by finite element method and experimental data,which indicates the reliability of the proposed iterative algorithm. |
