1 results about "Spherical model" patented technology

This invention discloses a method and system for constructing a microscopic model of recycled concrete based on a three-dimensional five-phase spherical model, belonging to the field of numerical simulation technology for building materials. The method includes: constructing a co-simulation environment and creating a new mortar matrix; setting the core particle size of natural aggregate, the thickness of the old interface transition zone, the thickness of the old mortar, and the thickness of the new interface transition zone; generating single-particle aggregates and recursively calculating the outer diameter of each layer; generating random spatial coordinates that satisfy boundary constraints; placing aggregates based on a random sequential adsorption algorithm and Euclidean distance interference judgment criterion; parameterizing the effective aggregates to generate four concentric spherical geometries and marking them according to preset naming rules; repeating the placement until the target volume is reached; and automatically aggregating spherical geometries of the same medium type into an explicit selection set using naming rules. This invention solves the problems of single-dimensionality, missing microphases, and low modeling efficiency in existing technologies, achieving high-precision and automated construction of the five-phase structure of recycled concrete, providing an accurate numerical model for subsequent mechanical property and durability analysis.
