The aim of this study is to evaluate 3D numerical simulation and 2D theory on a single edge notch cracked specimen loaded in mode I in light of experimental data. The three displacement components through the whole specimen were measured by Digital Volume Correlation coupled to X-ray micro-computed tomography. The theoretical approach gives higher results than the experimental ones, which means that the plane-stress theory is not relevant of the reality in this particular case. On the contrary, the numerical simulation made on the finite element software CASTEM gives results similar to the experimental ones with differences equivalent to the accuracy of the experimental method.
