  • Crushing of Soil Particles | Journal of Geotechnical Engineering | …

    Abstract. In order to understand the physics of the strength and stress‐strain behavior of soils and to devise mathematical models that adequately represent such behavior, it is important to define the degree to which the particles of an element of soil are crushed or broken during loading. The amount of particle crushing in a soil element ...
