The concrete can be treated as a kind of granular materials, so it is suitable to be analyze by the discrete element methods. If we want to apply the discrete element methods to analyzing the concrete materials,it needs to use the contact law for the granular materials with conforming binder.In this research,I try to deriving an approach solution between force and relative movement of particles.The approach solution is particularly desirable because it can be readily incorporated into discrete element methods for the analysis of a large assembly of particles.Then I make a comparison with the approach solution and finite element me
