Three test series of single-edge notched beams in three-point bending were conducted to evaluate the fracture energy of concrete. The fracture energy was determined from the area under the complete load versus load-point deflection diagram. The nonlinear Fictitious Crack Model was implemented in a finite element analysis, showing good agreement with the experimental data. By varying the notch depth and the beam depth it. Has shown that the fracture energy, traditionally presented as a material property, depends upon the specimen size and configuration. This is attributed to the energy dissipation in the process zone which is not accounted for in the analytical model.
