According to energy theory, the rock dynamic elastic modulus is the embodiment of dynamic elastic parameters under dynamic load, and its value reflects the quality of rock's elastic bearing performance; the rock damping ratio represents the ratio of the total energy consumed by the rock to its elastic strain energy during the single loading period.
