Description	In this paper, the authors present an original local fracture energy concept within a framework of effective crack model. Within this model the crack is modeled as an %22elastically equivalent notch%22 with a depth equal to the effective crack length a. The local fracture energy can be - within this model - determined using three-point-bend tests as a derivative of energy release rate with respect to the effective crack length a. As long as the local fracture energy exhibits a plateau, size-independent fracture energy can be determined. The main advantage of suggested method is that it does not require (contrary to other methods) testing of many samples of different shapes, sizes or notch to depth ratios, thus greatly simplifying the determination of the size independent fracture energy.
