This research aims to formulate and implement a continuous-discontinuous approach for
failure of quasi-brittle materials. This approach is based on a damage evolution law using only
physical parameters, which can be obtained through fracture and resistance tests without the need of
further calibration. Comparison with experimental results were performed to assess the accuracy and
efficiency. The tests simulated with the model were the three-point bending in a single edge notch
beam. The results obtained herein confirmed the efficiency and accuracy of the model in predicting
rupture behavior. Moreover, the model can provide results with equivalent accuracy to others in the
literature using fewer elements in the mesh.
