Crystal plasticity finite element modeling (CPFEM) is realized on the basis of crystal plasticity theory of rate dependent polycrystal constitutive relations. Initial orientations obtained by electron backscatter diffraction (EBSD) are directly input into crystal plasticity finite element model to simulating mechanical response and texture development of F. C. C. 1050 pure Al in nonaxial tensile deformation. Stress-strain curves of tensile deformation are analyzed. Predictions are both reasonable agreement and some little deviation with experiments. Texture evolution at tensile true strain 0. 25 and 0. 37 are predicted by two polycrystal models (Taylor-type model and finite element model). With the strain growth two types of fiber textures become sharper or stronger. Modeling results of textures are well accord with the experiment results.
