Prediction of Work-Hardening Behavior under Various Loading Paths in 5083-O Aluminum Alloy Sheet Using Crystal Plasticity Models

In the present study, crystal plasticity models applicable for reproducing work-hardening behavior under various loading paths of an A5083-O Al alloy sheet were examined. The consideration tension, reverse from compression to simple shear, and biaxial tension. accumulated-slip-based hardening model with extended Voce law provided good predictive accuracy uniaxial loadings. contrast, it could not reproduce anisotropic which was observed in experimental results. case dislocation-density-based models, both loadings tension reproduced fairly well when property interaction matrix considered. On basis these results, a new proposed, effects latent considered calculation accumulated slip. allowed prediction as model. This result suggested that more affected by modelling than choice internal variables hardening, i.e., slip or dislocation density.
