Summary

This paper investigates the penetration and relaxation behavior of JSC-1A lunar regolith simulant under cryogenic conditions. The study focuses on how ice content affects penetration resistance and force relaxation, with measurements conducted at specific temperatures and pressures. The results suggest ice content significantly influences mechanical properties, with critical ice content identified between 1% and 3%. The paper investigates the mechanical behavior of JSC-1 lunar regolith simulant under cryogenic conditions, focusing on its response to compression and shear. The study employs a combination of experimental testing and numerical modeling to understand the material's properties and behavior at low temperatures. Key findings include the significant impact of temperature on the mechanical strength and deformation characteristics of the simulant, as well as the importance of microstructural changes in determining its performance under extreme conditions. This paper investigates the penetration and relaxation behavior of JSC-1A lunar regolith simulant under cryogenic conditions.
