The paper discusses the use of a lunar simulant, LUNAR-1, to study the mechanical behavior of lunar regolith under various conditions. The simulant was subjected to compression and shear tests to understand its response to different stress states. The results indicate that LUNAR-1 exhibits brittle behavior under compression and shear, with significant deformation and failure observed at high stress levels. The study also highlights the importance of simulant composition in accurately representing the mechanical properties of lunar soil.
