3D meso-scale modeling of reinforcement concrete with high volume fraction of randomly distributed aggregates

An effective numerical method is proposed in this paper to generate a meso-scale composite model of reinforcement concrete (RC) which contains aggregates with random size and shape based on Voronoi tessellation method. Besides the randomly distributed aggregates, the present model takes into account the reinforcement, compared with other conventional methods in finite element modeling of concrete. The shrinking algorithm with random shrinking...
