| Popis: | International audience; The present work aims at exploring self and latent hardening for FCC polycrystals under complex loading paths at room temperature. A relative quantification of the effect of the different interaction types between the 12 slip systems on the hardening is notably proposed. Combinations of simple loading sequences, such as tension and simple shear, with different orientations with regard to rolling direction, are considered. The material used is a 0.5 mm sheet of hot rolled OFHC copper. Two single crystal laws are independently identified. The experimental data are respectively compared with a finite element analysis, and two mean field models: the β-rule and the Kröner's model. A new order of the hardening matrix coefficients is proposed for FCC materials. Both identifications are compared and give rise to the same trend. |
