Laboratory test. Comparison between the experimental and the numerical results in terms of extension of the damage induced by the fluid pressure. a Extension of the damaged zone observed in the experiments [4]. b Visualization of the distribution of the damage in terms of magnitude (dark red color corresponds to 0.5 mm) of the opening displacements as obtained from the numerical simulation, on a quarter of the numerical model showing the different extension of damage on the symmetry planes
