The origin of cube texture during recrystallization of medium to high stacking-fault energy FCC metals has been debated for several decades. However, evolution of the cube component during deformation is not studied well and hence, it is still unclear what are the favorable nucleation sites for the cube oriented grains. To resolve this issue, we applied a 3D full field crystal plasticity model utilizing a dislocation density based constitutive theory for the simulation of plane strain compression of polycrystalline copper. Simulation results reveal that some of the grains with initially non-cube orientations developed the cube component during the deformation. Local deformation conditions play a major role in the development of such cube oriented deformed regions. Analysis of the disorientation angle and the dislocation density difference with the neighboring locations shows that the cube component developed during the deformation can play a significant role during nucleation.
