Abstract: The analysis of the formation of shear band will benefit both the study of the engineering behavior of soils and the evaluation of their stability . Based on elasto-plastic model proposed by Sekiguichi and Ohta, the influence on shear band formation of the rotation of principal stress directions is investigated. It can be concluded that the directions along which local shear deformation may occur most probably depend on the rotation angle of the principal stresses, but the rotation of principal axis doesn’t contribute significantly to the instability by localization of the deformation .

Key words: shear band, rotation of principal stress, localization
