Testing Analysis on Rock Fatigue Life Due to Affecting Factors under Uniaxial Compression

Abstract:

Using the rock mechanics multi-function testing machine named RMT150B, the testing study on rock fatigue life due to different affecting factors under uniaxial compression condition are accomplished. It is the study emphasis that the influence mechanism of rock sample fatigue life due to different stress amplitudes, waveforms and frequencies .It shows that the stress amplitude, waveform and frequency can all remarkably affect the rock fatigue life. The influence essential reason of rock life due to different stress amplitudes and waveforms is the different dissipation of energy. And the influence essential reason of rock life due to different frequencies is the different loading rate of speed.
