摘      要：A numerical analysis of bifurcation in shear-band pattern is presented to help understand the distributions of the velocity variation in the shear band. Comparison with the results of analytic method indicates that: (1) the critical strain is irrelevant to the relative width of the shear band; (2) the variations along the direction normal to the band have indeed the controlling effect whilst the effect of variations along the tangential direction is negligible.
