Abstract: This work deals with numerical simulation of the mechanical behaviour of concrete using a homogenised damage model based on the concept of Representative Volume Element (RVE). The RVE is composed of phases with different mechanical behaviours leading to heterogeneous characteristics on the microstructure level. We adopt a simple damage model capable to simulate the behaviour of the cement paste and transition zone while the aggregates are modelled as linear elastic material. To perform the numerical analysis, a based homogenisation technique is used to obtain a damage model that represents the macromechanical behaviour of the material. Results show the capabilities of the model to capture complex phenomena including a comparison with experiments tests performed in concrete specimens.
