A Constitutive Model of Sand Considering the State-Dependent and the Effect of Direction of Principal Stress
Based on the theory of critical state,the state parameter considering the direction of principal stress during shear is introduced into dilatancy equation and the plastic hardening modulus expression to develop a new constitutive model for sand which can display the influence of the shearing direction of principal stress.By comparison with the related experimental data and analyzing,the method on simulating the stress-strain relationship under the different shearing direction of principal stress is proved to be correct and accurate.
