Based on the finite deformation theory of single crystal plasticity, the slip-band trace on the specimen surface of single crystal copper tensioned uniaxially is modeled by FEM with a finite deformation algorithm, and three dimensional plastic slipping is observed in computational simulation for single crystal copper specimen tensioned in different orientations. Through the geometric analysis of intersect-line between the active crystallographic slip-plane with specimen surface, we exhibit different slip-band traces on specimen surface, which are believed to come from different slip-planes activated by tension in different orientations. Good agreement between FEM results and experiment measurements indicate that the crystalline plasticity based computational simulation is available to study the formation of slip-band trace on the specimen surface of single crystal.
