文摘

The mechanical properties, failure forms and AE responses of SP are studied. The damage fragment evolution mechanism and effect of particle size are analyzed. The coupling relationship between mechanical parameters and AE of SP are obtained. Provide the scientific basis for better selection and matching of simulating material.
