Fracture Energy for Three Point Bend Tests on Single Edge Notched Beams: Proposed Evaluation

Abstract

The research in fracture mechanics of concrete is reviewed in an attempt to reconcile the different and sometimes contradictory approaches for evaluation of the fracture energy, Gf. An improved method to measure Gf for beams in three-point bending is presented. This method is expected to provide a more reliable characterization of the fracture toughness of concrete.
