The deformation of an assembly of individual particles mutually in contact when subjected to repeated loading was studied with respect to the change of the structure of the mass. The two-dimentional model experiment was performed and the particle movement, the angle between interparticle contact plane and horizontal plane and the void ratio were investigated. As the deformation increases under repeated loadings, frequency distributions of the direction of particle movements and of the direction of interparticle contact plane change their shape. It was found that the deformation process of the granular materials consists of two different stages, i. e. initial compaction process and succeding flow process.
