Summary

This paper investigates the effect of grain size distribution on the stress-strain behavior of lunar soil simulants. Four simulants were tested using static simple shear tests to evaluate shear strength, dilatancy, and volume change behaviors. The study highlights the influence of gradational parameters such as mean grain size, coefficient of uniformity, and fines content on geotechnical properties. The paper investigates the impact of grain size distribution on the mechanical behavior of lunar regolith simulants under simulated lunar conditions. The study employs a combination of experimental testing and numerical modeling to evaluate the effects of varying grain size distributions on the strength, deformation, and failure characteristics of the material. The results highlight the importance of grain size distribution in determining the mechanical response of lunar regolith simulants, with implications for the design of lunar habitats and equipment.
