Abstract
The investigation on the physical properties of coral sands is very important for their transportation and application. Here the micro friction and adhesion behavior of coral sands from South-China-Sea was investigated by atomic force microscopy (AFM). Variation of the friction coefficient was experimentally measured when a coral sand particle swept across different materials including mica, sapphire and SiO2. Besides, the interaction between coral sand particles and substrate was simulated by a finite element method (FEM).
