Textures formed by tensile deformation at ambient temperatures and texture induced crystallite microstrains of pure copper were simulated using the full plastic Taylor-Bishop-Hill theory and an elastic unloading process described by the linear elastic Voigt model. The results of the simulations are compared to inverse pole figures experimentally determined by X-ray diffraction and εφψ vs. sin2ψ curves experimentally determined using high energy synchrotron radiation. It is shown that the texture evolution has a strong influence on the crystallite microstrains and produces non-linear strain curves. The microstrain distribution depends on the deformation mode and the lattice plane.
