The flexural strength obtained by the numerical models developed by the LDP and the KCC automatic input mode lie significantly out of the 95% Confidence Intervals of the average value, as predicted from statistical elaboration of experimental data, while, this issue is solved by implementing the calibrated input mode of KCC. The coupling of SPH and FEM was proved to be a reliable method to simulate crack generation. This method was shown to be an effective solution to simulate several rock mechanics applications that deal with large deformations, e.g. penetration, drilling, perforation, etc. (a) (b) (c)
