Summary

This paper investigates the geotechnical and shear behavior of three novel lunar regolith simulants: TUBS-M, TUBS-T, and TUBS-I. The study focuses on their engineering and flow properties under various conditions, including shear tests, particle size analyses, scanning electron microscope observations, and density investigations. It highlights the importance of fine lunar dust (<25 µm) in cohesion and compression, and discusses correlations between stress peaks and damage mechanisms in larger grains. The paper also addresses discrepancies in particle size measurements across different methods. The paper discusses lunar regolith and its importance for sustainable lunar habitats, focusing on geotechnical and shear behavior of novel simulants TUBS-M, TUBS-T, and TUBS-I. It highlights the need for regolith simulants to support in-situ resource utilization (ISRU) and space exploration technologies. The paper discusses the importance of lunar regolith simulants in space exploration, particularly for the development of technologies related to in-situ resource utilization (ISRU) and construction on the Moon. It highlights the need for accurate simulation of lunar regolith properties to sup
