Generally localization of deformation is considered as boundary value problem in numerical analysis. Finite element analysis using soil-water coupling and finite deformation theory can express the shear band numerically. In this research, it is shown that the finite element analysis, using the constitutive model considering the influences of density and confining pressure, based on small deformation theory can express the localization of deformation for both the conditions of soil-water coupling and soil ground without water. Mechanism of development of the shear band is considered by investigating the behavior of each element.
