The onset of shear band in FCC crystalline material is discussed by perturbation method with crystal plasticity theory. The critical condition can be calculated after the perturbation distribution ratio is evaluated numerically. Latent hardening can be included in the formulation. The shear band prediction routine is implemented in finite element polycrystal model. Plane strain tension after pure shear is analysed in single crystal. The results show the effects of crystal orientation and latent hardening on the occurrence of shear band.
