Abstract The initial morphology and mean orientation of columnar-grains of pure copper was obtained by electron backscattering diffraction (EBSD). A finite element model based on crystal plasticity was established to simulate the orientation and deformation band evolution of individual grain during uniaxial compression. Corresponding compression test was carried out to obtain experimental data which showed the actual evolution of orientation and band morphology in the polycrystalline sample. A series of statistical results of grain orientation evolution were obtained, and the calculated results were compared to experimental data.
