Synopsis: This open access book provides a detailed exploration of how dynamic disturbances, such as those caused by blasting or seismic activity, affect the damage and failure mechanisms of rocks. When excavation is carried out under high stress environment, the external disturbance will change the stress field of the rock, which may lead to potential engineering damage such as large deformation and large displacement of the free surfaces of the engineering surrounding rock, and even cause instability damage, rockburst, and other engineering disasters. From 1960s onward, the subject of progressive damage and failure of rock materials has been extensively investigated to prevent and control geological disasters and engineering accidents. However, the existing researches usually did not take the effects of low-frequency dynamic disturbances on the mechanical properties of rock into consideration. Rock mechanics researchers, such as graduate students, doctoral students, or academics, need to understand the complex interactions between dynamic disturbances and rock integrity. They require up-to-date knowledge of the latest research findings and models to predict rock behaviors accurately.
