| Abstract | The measuring of the fracture energy of concrete was thoroughly analyzed by several researches with regards to obtain a size-independent value. In this work prismatic notched specimens were subjected to three-point bend tests according to the experimental requirements of two main methods. Three different kinds of notched beam were manufactured. Two of the specimens were tested according to the simplified method proposed by Abdalla and Karihaloo. The other type of specimen was subjected to three-point bend tests with the self-weight compensation according to the method proposed by Elices et al. The size-independent fracture energy of concrete obtained with each method was analyzed. The two values were in excellent agreement which can thus be regarded as a true property of the material. It is therefore concluded that either method can be used to obtain a unique value of the size-independent fracture energy of concrete. |
