A Rate-Dependent Viscous Model for Sand

摘要：

　　Experimental results show the dense sand exhibits very distinct viscous characteristics.The main viscous aspect of sand includes the effect of the strain rate change,creep and stress relaxation.In order to properly simulate the viscous characteristics,especially the temporary effect of strain rate change,a new visco-elastoplastic constitutive model is presented.
