The contact tensor and modified stress tensor for granular materials are proposed in order to account for the internal fabric state and internal stress state. The fundamental features of these tensors are discussed and the evolutions of them for monotonic and cyclic loadings are examined. The significance of them as internal variables for the description of mechanical behavior of granular materials is discussed. The simple kinematics of granular materials is proposed and the dilatant behavior is discussed. The spin tensor, which has been neglected in the kinematics of granular materials, is also studied.
