Studying the performance of concrete and in particular its fracture properties is necessary for assessing the integrity of existing structures. Concrete fracture mechanics parameters are also needed in order to model concrete structures subjected to extreme loading such as earthquakes. The main objective of this paper is to develop a new methodology for the identification of fracture parameters using Digital Image Correlation (DIC) for measuring crack extension. Experimental results from the wedge splitting tests (WST) are used as reference where the crack mouth opening displacement (CMOD) is measured by clip-on-gauge. These results are subsequently compared to the data obtained from the Digital Image Correlation using the ARAMIS system. The identification of the fracture properties is carried out by solving an inverse problem. The associated forward problem is based on the cracked hinge model capable of taking into account the softening phenomenon. This approach approximates the behaviour of WST and allows an analytical solution. The results of inverse identification are confirmed using the finite element analysis (FEA) along with the obtained fracture energy.
