Abstract
The main aim of this paper was to investigate a complex fracture process in a concrete beam subjected to 3-point bending test by means of the 2D meso-scale FEM with 4-node cohesive elements embedded in the initial mesh of 3-node solid elements. The material heterogeneity was taken into account by considering 3 different phases (aggregate, cement matrix, ITZs) on the basis of randomly generated internal structure of concrete and assigning different material properties to each phase. The effect of the shape and content of the aggregate particles was comprehensively analysed in the paper. In addition, parametric studies were carried out for different fracture properties of the cohesive elements.
