Experimental and numerical determination of the dynamic fracture energy of concrete
article
In an experimental programme, impact tensile tests were performed on notched and unnotched specimens in a Split Hopkinson Bar apparatus to determine the dynamic fracture energy of concrete. The results have been compared to static experiments. In order to distinguish structural and material response the experiments were numerically simulated. That resulted in the observation that the dynamic fracture energy and the static fracture energy are approximately equal.
