Wave Velocities and Poisson Ratio in a Loose Sandy Martian Regolith Simulant Under Low Stresses: 2. Theoretical Analysis
Résumé
• A novel theory based on contact mechanics was proposed to calculate Vp and Vs of uniform granular materials. • The theory considers the roughness of the particles, the stress, the porosity of the granular assembly and the properties of the grains. • Theoretical results agree with experimental measurements on loose samples of Fontainebleau sand used as a Mars regolith simulant.
