In order to elucidate the shearing mechanism in granular materials such as sand and gravel, it is necessary to have a correct understanding of the fact that these materials consist of individual grains. In this paper, two-dimensional shear test was carried out by using the two-dimensional horizontal stack of alminium rods, and examined the shearing behavior of granular materials from the microscopic point of view. And in these examination, the change of distance between particles, the relative rotation between particles and the rotation of individual particles were mainly chosen as factors to control the shearing mechanism of granular materials.
