Abstract

Abstract

According to the mechanical properties and components of concrete from the mesoscale viewpoint, a simple and high-efficiency method based on 3D-Voronoi is proposed to construct realistic meso-structure model of concrete. In this paper, 3D mesoscale numerical simulation is conducted using damaged plasticity modeling under quasi-static and dynamic load. The simulation results resemble the corresponding experimental results both in strain-stress curves and failure modes. The current method can simulate static and dynamic mechanical properties well. In addition, the proved 3D model can provide an effective approach in elucidating fundamental mechanical behavior of concrete-like materials.
