Currently most rock fatigue damage models aim to calculate damage factor which cannot be directly used for estimation of peak strength changes. If reduction of peak strength links the cyclic loading directly, the evaluation of peak strength reduction under dynamic loading problem would be more effective. We numerically simulate rock damage under different cyclical stress amplitudes and average stress for the relation between peak strength reduction and number of cyclic loading. The primary damage model in terms of peak strength reduction under different cyclical stress amplitudes and average stress is constructed.
