ANALYSIS OF DEFORMATION MECHANISM OF PARTICULATE MATERIAL AT PARTICLE SCALE

Abstract

In this paper the shearing mechanisms for particulate material are investigate at the particle scale. Then, the coefficients in the basic equation of Markov process, which has been explained in the previous paper (Kitamura, 1981), are quantitatively evaluated by introducing the concepts of the potential barrier and the potential slip plane. It is revealed that these concepts play important roles for the investigation of shearing process of particulate material at the particle scale. The values of these coefficients can be obtained by using the energy transferred into or out the particulate material, the initial void ratio, the grain size distribution, the coordination number and the frictional coefficient.
