dc.description.abstract | In order to analyze the time-dependent spring-back behavior of the aluminum alloy 6022-T4 sheet, the viscoelastic/plastic constitutive law was applied by utilizing a linear viscoelastic/plastic model previously developed. As for the plastic deformation, the combined isotropic-kinematic hardening law was used to represent the Bauschinger behavior and transient hardening, while a non-quadratic anisotropic yield function, Yld2000-2d, was applied to account for anisotropic yield behavior. The numerical formulation was developed based on the incremental deformation viscoelastic/plasticity theory and then, the constitutive law was implemented into the ABAQUS/Standard commercial finite element program using the user-defined material subroutine, UMAT. The viscoelastic behavior was characterized by the creep test above the initial yield stress level, while anisotropic yielding and hardening parameters were obtained by the uniaxial tensile test. The constitutive law and the formulation were successfully validated for time-dependent springback in the draw-bend test. | - |
