n current study, computational homogenization-based crystal plasticity (CP) modelling was presented to determine the
deformation behavior of a novel third-generation AL-Li alloy 2060-T8 at room temperature, strain rate of 0.01s
-1
and various
loading directions. The computational homogenization strategy used a representative volume element (RVE) which describes the
real microstructure of AA2060-T8 sheet to consider the in grains deformation behaviour. Besides, a periodically boundary condition
was modified to consider both deformation induced anisotropy and the geometrical anisotropy. The initial microstructures and
micro-textures of the AA2060-T8 sheet were determined by EBSD measurements, as well as used to build up the RVE model.
The material parameters used in CP modelling was determined from the stress-strain curve obtained from the tensile test at
strain rate of 0.001s
-1
and loading direction of 30° with reference to rolling direction. The results obtained from computational
homogenisation strategy keep a remarkable agreement with the results determined from experimentation. In conclusion, the
computational homogenization based CPFEM is able to predict the deformation behavior and capture the anisotropic response
of AA2060-T8 sheet at various deformation conditions.
