Notes:
A previously proposed single crystal hardening law is applied to the prediction of responses of polycrystalline material under non-proportional cyclic loading. In this paper, the Kroner, Budiansky and Wu model is adopted and the relevant numerical schemes for both the iteration related to the non-proportional loading paths and the search of active slip systems are established. Two typical engineering materials: oxygen-free, high-conductivity (OFHC) copper and 316 stainless steel, which differ greatly from each other in microstructure, are used for predictions and comparisons with experiments. Loading paths include the symmetric tension-compression cycle, the circular cycle and the rectangular cycle. The behaviour of 316 stainless steel, at both room and elevated temperature is modelled. Comparisons show that the predictions are in quantitative agreement with the corresponding experiments for all the cases mentioned above. In addition, comparisons of different single crystal hardening laws are also presented.
