Experimental Characterization And Numerical Modeling Of The Three-dimensional Anisotropic Behavior Of A Thick Sheet Aluminum Alloy AA2024-T351 Using Multi-scale Approaches

The purpose of this work is to evaluate the anisotropic behaviour of an AA2024-T351 thick plate using three different multi-scales approaches: a macroscopic unified model (based on HILL 48 yield loci), a multi-mechanisms model and a polycrystalline one. The experimental results obtained from uniaxia...

Summary:The purpose of this work is to evaluate the anisotropic behaviour of an AA2024-T351 thick plate using three different multi-scales approaches: a macroscopic unified model (based on HILL 48 yield loci), a multi-mechanisms model and a polycrystalline one. The experimental results obtained from uniaxial tensile tests are first described. Thereafter, theoretical formulations and identification of studied numerical elastoplastic models are presented. Finally, finite element simulations of tensile tests and analysis of drawing process are performed.
