Abstract: A numerical study on shearing movement of granular system with a dragging solid body on top is presented.It focuses on friction between body and particles.It shows that friction coefficient varies with dragging velocity.This behavior,totally different from interaction between two solid bodies,implies complexity of granular system.

Key words: granular flow, friction, numerical simulation, molecular dynamics modeling
