Increasing number of experimental studies exist corroborating the tendency to liquefaction of granular media subjected to continuous rotation of principal stress axes under constant amount of shear stress. Many loading conditions in the practical problems of engineering can be named as the examples of this manner of loading. Therefore, further development of advanced plasticity models is necessary. Herein, a plasticity onstitutive model for simulation of liquefaction of granular soils under continuous rotation of principal stress axes is presented in the generalized plasticity framework. It is shown that the model can satisfactory simulate the liquefaction behavior of sandy soils subjected to continuous rotation of principal stress axes.<\div>
