Plain concrete is made of cement matrix and aggregates. The current numerical model researches mostly consider the cement matrix and ignore the existence of coarse aggregates, which is not consistent with the reality. In view of that, this article uses ABAQUS as the platform to establish a meso-concrete damage model based on the concrete coarse aggregates and CDP (Concrete Damaged Plasticity) model constructed in Python language. The results show that: (1) The main failure mode of concrete model is shear failure, and the crack is about 45° to the vertical plane. (2) Under the action of the load, multiple micro-cracks are formed at the end of the concrete, which are gradually extended to each other, and finally a macroscopic large crack is formed. (3) The damage model proposed in this article is in line with reality and provides guidance for concrete damage research.
