 Abstract:             Rock dynamics studies the response of rock materials and rock masses under dynamic loading conditions. In the last a couple of decades, the development of experimental and computational techniques has been able to capture the progress of fracturing in microsecond steps, allowing the exploration on how the fracture is initiated, propagated and branched, leading to the development of new scientific theories. A summary of these developments on rock dynamic testing, modeling and theory will help the scientific and engineering community to consolidate the understanding of rock dynamics and to apply
