The following figures show these comparisons for the case of 4-point bending with 2D and 3D simulations, and 2D simulations for the 3-point bending tests. a) Specimen 4 b) Specimen 5 c) Specimen 6 d) Specimen 7 e) Specimen 8 f) Specimen 9 Figure 14 : Comparison of the pre-crack resisted and the simulation for 2D 4-point bending.
