循环载荷下随动硬化模型的数值迭代算法
Numerical iterative algorithm of kinematic hardening model under cyclic loadings
摘要
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 or-thogonal 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-Ab-del-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 , w hich indicates the reliability of the proposed iterative algorithm .关键词
