摘要

Texture is an important factor for sheet metal formability. Compared to symmetric rolling, asymmetric rolling (ASR) is capable to shift the shear-type texture toward the sheet center. To investigate the texture evolution after ASR, the so-called full-field crystal plasticity model, crystal plasticity finite element method, was adopted, in which the plastic deformation and texture are fully coupled. Developed texture was partitioned into rolling-type and shear-type textures, and the area fractions and through-thickness distribution of these two textural types were investigated. The nonuniform distribution of texture and plastic deformation along the thickness was revealed. Finally, the effects of asymmetric ratios and friction coefficients on texture and plastic deformation were discussed.
