The distribution law of contact force, which makes the determination of mean contact force at each contact possible, is successfully applied to calculate the theoretical value with respect to the mobilized stress ratio and the inclination angle of the maximum principal stress axis in the simple shear test. The rotation of the principal stress axes during simple shear occurs in the process of increasing stress ratio, and the principal axes of stress and of strain increment do not generally coincide with each other, at least up to the peak stress ratio. The equations obtained theoretically accord well with the experimental results performed by the present authors and Roscoe, et al. The same principle in regard to the mechanism of strain hardening is also applicable to the direct shear test of sand.
