Constitutive Modeling of Granular Geo-Materials Under High-Speed Impact

Matsushima, Takashi / Sato, Kan

Abstract A constitutive model of crushable granular geomaterials subjected to high pressure/high speed compression is proposed in this study. The proposed model is based on a micromechanical elasticity model of mono-disperse granular materials [2], and it is extended into well-graded ones in a simple manner. A geometrical recursive equation is introduced to describe the confined crushing process of granular materials. High-pressure Equation of States of solid [21] is also incorporated into the model. The basic response of the proposed model is compared with some experimental data.
