Summary

This paper quantifies mechanical property changes in lunar soil simulant due to drilling disturbances. It measures density and internal friction angle changes, identifies key drilling parameters, and discusses challenges in lunar drilling operations. The study uses theoretical soil mechanics and experimental data to analyze drilling impacts on lunar soil properties. This paper discusses the mechanical properties of lunar soil and the disturbance caused by drilling. It proposes a method to quantify drilling disturbance using penetration resistance measurements. The study focuses on simulant preparation, mechanical property analysis, and the relationship between drilling parameters and disturbance effects. The paper discusses the quantitative measurement of changes in mechanical properties of lunar soil simulant caused by drilling disturbances. It includes equations for calculating stress and friction forces but does not provide specific simulant names, samples, experiments, or properties beyond theoretical formulations. The paper discusses mechanical properties of lunar soil simulant under drilling disturbances, focusing on friction, soil pressure, and bearing capacity. No simulants
