Microstructurai Modeling of Granular Materials with Inner Forces

摘要：

　　In this paper,we present a method to take into account the existence of inner forces between grains and their influence upon the mechanical behavior of granular assemblies.Two examples were retained.The first one concerns unsaturated granular materials for which we have considered capillary forces depending on the degree of saturation.The second one concerns extraterrestrials soils for which surface energy forces,such as Van der Waals forces,cannot be neglected due to tiny atmospheric pressure.
