The inclination angle ψ of the major principal stress axis to the vertical direction is deduced from a simple relationship ; τ/σ_N=κtan ψ, which is derived from theoretical consideration (Oda and Konishi, 1974) and verified by Cole's experimental results. The value of κ is a material constant for a given sand which is dependent only on the interparticle friction angle. By using this relation, the principal stress parameters such as mean stress (σ_1+σ_3)/2 and maximum shear stress (σ_1-σ_3)/2 are easily deduced from the shear stress τ and the normal stress σ_N acting on the horizontal shear plane in a simple shear test or even in a direct shear test.
