The relationship between dynamic strength and strain rate and damage to rock materials subjected to dynamic cyclic loading

Induced and natural earthquakes will put the rock underground engineering in a state of dangerous destruction during the mining of resources, such as oil and gas. The form of seismic load is regarded as a dynamic cyclic load in general. Generally, the strain rate has a significant influence on the mechanical properties of rock materials, such as strength, subjected to dynamic load and rock materials will suffer damage under cyclic loading;...
