| Abstract: | On the basis of the sufficient consideration of vectorial characteristics of stress, a new nonlinear constitutive model for
cohesionless soil under plane strain and 3-D conditions was presented in a way that the action effects of stress vector are
decomposed into the action effect of mean effective stress and that of the stress ratio vector (ratio of deviatoric stress
vector to mean effective stress). The constitutive model can take account of the influence of both numerical and directional
changes of stress vector on deformation of soil simultaneously, and is applicable of both static and dynamic loading.
