Analysis of Slip-Band on Specimen Surface of Polycrystalline Copper under Tension

Abstract:

Based on the crystal plasticity theory, the slip-band traces on the specimen surface of polycrystalline copper tensioned uniaxially are investigated by using the finite deformation numerical algorithm, and the statistical distributions of the inhomogeneous strain and stress in the specimen are analyzed. The tension deformation of the polycrystalline specimen is simulated by the three dimensional FEM. Through the geometric analysis of intersect-lines between the active crystallographic slip-planes and the specimen surface, the different slip-band traces of the specimen surface are calculated and discussed. According to the results, it is confirmed that the crystal plasticity theory is feasible to study the deformation of the crystalline material.
