Abstract
A modeling method for a high-density discrete particle multiphase system, including the following steps: determining a model boundary; drawing up a volume sum of particle phases within each size range in the model; generating compact models of particle models within all size ranges; expanding the particles in the compact models; and obtaining a high-density particle accumulation model. The method can be used for modeling of meso-structures of particle reinforced composite materials, granular materials in soft matter, particle accumulation materials and the like, and can also be extended to short fiber reinforced composite materials and the like. The method solves the modeling problem when the particles intersect with the model boundary, and can be applied to the modeling and analysis of composite specimens with machined surfaces.
