Summary

This paper investigates mechanical energy evolution and damage mechanisms of LPBF-printed lunar regolith simulants for Chang E-8 mission ISRU. It reports mechanical properties, strain behavior, and energy dissipation stages in mare and highland simulants. The study includes 3D-DIC analysis and an energy-based damage model. This study investigates the mechanical behavior and energy transformation characteristics of lunar regolith simulant printed using laser powder bed fusion (LPBF). The research focuses on microstructural analysis, mechanical response, strain evolution, and energy damage mechanisms under uniaxial compression. The findings contribute to understanding the performance variability and failure modes of lunar regolith simulants, which is crucial for sustainable lunar habitat development using in-situ resource utilization (ISRU) technologies.
