Abstract: Strain localization of soils as a stable behavior of soils can be understood as a bifurcation in the macroscopic constitutive properties in a special stress state. In this paper, a 3-D analytical solution for the criterion of onset of strain localization is deduced based on the finite deformation theory. The theoretical analysis shows that, onset of strain localization always occurs in the softening regime of constitutive response under axisymmetric conditions; and inception of strain localization generally occurs in the hardening regime under plane strain conditions, and shear bands’ orientation of theoretical prediction exhibits an agreement with that suggested by Arthur et al[1].

Key words: strain localization, bifurcation, shear band
