Summary

This paper describes the 3D shape characterization and image-based DEM simulation of the lunar soil simulant FJS-1. The study uses high-resolution micro X-ray CT to visualize 3D grain structures and applies a new image-analysis procedure to identify individual grains. The results show good agreement between simulated and experimental slope angles, and the paper discusses the impact of grain parameters on slope stability. This paper describes the 3D shape characterization and DEM simulation of the lunar soil simulant FJS-1. The simulant was produced by crushing Mt. Fuji basalt and adjusting grain size to match lunar soil. The study uses micro-X-ray CT and image analysis to model grain shapes for DEM simulations. Key properties include grain size distribution, angular shape, and high shear strength. This paper presents 3D shape characterization and DEM simulation of the lunar regolith simulant FJS-1. The study focuses on grain size distribution, shape analysis using Zingg diagrams, and image-based modeling for DEM simulations. The paper discusses erosion processes, cluster labeling, and surface error indices to evaluate model accuracy. This paper presents a DEM simulation of the luna
