英文摘要In this work, we propose a revised Chaboche model based on a crystal plasticity multiscale approach. From our experiments, 316L steel exhibits two plasticity characteristics at room temperature during the cyclic loading: varied plastic modulus in strain-controlled cycling and continuous growing ratcheting strain in stress-controlled cycling. These characteristics cannot be predicted by using the classic Chaboche model. To modify this model, we used a crystal plasticity multiscale approach to see the microstructure effect on these characteristics. The result shows that the viscous effect, which is ignored in the classic model, plays an important role in stress-controlled cycling. With the multiscale simulation results, we revise the Chaboche model in two folds: a static recovery item is included in the kinematic hardening rule to consider the influence of viscosity on ratcheting; the dynamic recovery term is varied with the accumulated plastic strain for the change of plastic modulus during the straincontrolled cycling. With the revised model, we show that the strain- and stress-controlled cyclic behaviors from experiments can be well predicted. Also, the application of the revised model in integrated structural analysis is discussed.
