Dynamic Fracture of L and CT Concrete Specimens: Numerical and Experimental Studies

To confirm the findings of recent numerical studies and to obtain the experimental evidence on dynamic fracture of concrete, experimental tests were performed on L- and CTspecimens. The experiments fully confirmed the results of previously performed numerical studies. It is shown that inertia effects are responsible for progressive increase of resistance, crack branching and rate dependent crack propagation. The presented, relatively simple, tests can be used to check whether numerical model is able to realistically predict complex phenomena related to dynamic fracture of concrete.
