Abstract：Based on crystal plasticity theory, the slip-band trace on the specimen surface of single crystal copper tensioned uniaxially is investigated by applying FEM associated with finite deformation numerical algorithm, and the three dimensional plastic slipping is simulated for single crystal copper specimen tensioned in different orientation. Through the geometric analysis of intersect-line between active crystallographic slip-plane with specimen surface, the different slip-band trace of the specimen surface is calculated and discussed, which is brought by tension in different orientation that leading different slip-planes are activated. According to the analyses of specimen surface slip-band, it is confirmed that the crystalline plasticity simulation is available to research the processes of slip-band trace formed on specimen surface of single crystal.
