The properties of rocks under dynamic loading are important for the study of a whole range of rock mechanics and rock engineering problems, including blasting, protective design, explosives storage, rock bursts and seismic events. The propagation of dynamic stress waves in the ground, response of rock tunnels to dynamic load, dynamic support design and damage assessment all require a good understanding of the behavior of rocks under dynamic loading. Due to the transient nature of dynamic loading, the dynamic tests of rock material are very different from static tests.
