Summary

This paper describes a novel specimen preparation method for TJ-1 lunar soil simulant in hollow cylinder apparatus (HCA). The method combines multi-layering dry-rodding with a new under-compaction criterion. The simulant's mechanical behavior under different stress conditions is studied, showing the influence of principal stress direction, deviator stress ratio, stress level, and intermediate principal stress coefficient on its strength and deformation properties. The paper presents a novel method for the preparation of lunar regolith simulant, which is essential for simulating the lunar surface environment for space missions and research. The method involves the use of a combination of natural and synthetic materials to create a simulant that closely mimics the physical and chemical properties of lunar regolith. The simulant is then tested for its suitability for various applications, including the testing of lunar rovers and other equipment. The results of the study indicate that the proposed method is effective in producing a high-quality lunar regolith simulant that can be used for a wide range of applications.
