This study presents a multiscale modeling framework linking different length scales to evaluate the anisotropic behavior of aluminum during the tube drawing process. A 3D-FEM model using ABAQUS software, including a Crystal Plasticity (CP) approach, was developed, and the multiscale methodology was used to achieve all the necessary parameters for this CPFEM model. This multiscale modeling framework starts with electronic scale calculations using the Density Functional Theory (DFT) approach to calculate the energy variation as a function of lattice parameters as well as the generalized stacking fault energy. Using calculated parameters, Modified Embedded Atomic Method (MEAM) calculates the anisotropic elastic constants and the required potentials for the Molecular Dynamics (MD) calculations. MD simulations are performed to generate mobilities for dislocations and drag coefficients. Utilizing the mobility values, the Dislocation Dynamics (DD) approach in the microscale computes the hardening parameters. UMAT subroutine allowed to combine the CP theory with the tube drawing FEM model and calculated elastic and plastic parameters at lower scales. The simulation results were validated using the measured texture and showed a good agreement with the experimental results.
