Sand-Steel Interface Friction Related to Soil Crushability
A ring shear apparatus is used to evaluate the interface behaviour between sand and steel up to an interfacial critical state. Four kinds of sands having a different mean particle size and crushability were sheared along the steels with various surface roughness at a given normal stress level. Further, the individual particle strength tests were also conducted to investigate the degree of soil crushability. Test results are discussed in the context of the normalized surface roughness and soil crushability index. As a conclusion, it is indicated that, depending on the relative roughness, the crushability has a strong influence on the friction behaviours between sand and steel, particularly in the large deformation state.
