In this study, the behavior of a 5383 aluminum alloy is investigated. An experimental campaign, including uniaxial tension and free bulging tests, is performed to characterize the mechanical properties. The BBC2003 yield criterion with a composite hardening model is employed to describe the constitutive behavior. The model is implemented in the ABAQUS finite element solver with a user subroutine. The identified model is validated by comparing numerical and experimental results obtained for the hot forming of a complex shape specimen at 673 K and 0.001 s-1. The experimental and numerical results (strain field and thickness distribution) are in good agreement.
