“…The modified constitutive model considering the anisotropic hardening was implemented in Abaqus/Standard via user subroutine UMAT with the fully implicit backward Euler return mapping algorithm, and the successful application of the algorithm for anisotropic hardening was also reported in Ref. [18]. The FE analysis of tension leveling was conducted using the FE model mentioned in section 2 with the modified constitutive model.…”

Tension leveling is an important industrial process to eliminate the flatness defects and residual stresses of metal strips to provide high-quality sheet metals for subsequent sheet metal forming. The finite element (FE) method can be applied to elucidate the effects of process parameters on the quality of sheets after tension leveling for various materials. In our previous investigation, an accurate FE model considering the anisotropy and cyclic plasticity of materials has been established for the elastic-plastic FE analysis of tension leveling. In this study, we further studied the effects of the yield point and plastic anisotropy on tension leveling using the FE model established in our previous investigation. Aiming at improving the accuracy of simulation, a modified constitutive model was developed to describe the anisotropic hardening of materials under cyclic loading. The modified constitutive model was implemented into Abaqus/Standard as a user-defined material (UMAT) subroutine to simulate the development of the anisotropy in materials during tension leveling. The modified model was also applied to the FE analysis of sheet metal forming processes to demonstrate its simulation capability and accuracy.
