Waveform Effect on Fatigue Properties of Intact Sandstone in Uniaxial Cyclical Loading

Original language description

The effect of loading waveform and amplitude on the fatigue behaviour of intact sandstone was investigated using uniaxial cyclic loading conditions in the laboratory. In the first set of experiments sinusoidal, ramp and square waveforms were used at loading frequency of 5 Hz and peak amplitude of 0.05 mm. In another set of experiments, tests were conducted at a range of amplitudes varying from 0.05 to 0.3 mm at 5 Hz frequency using sinusoidal and ramp waveforms. It was found that loading waveform as well as amplitude is of great significance and affects the rock behaviour. It was found that fatigue behaviour is a function of the cyclic energy of the load and the shape of the waveform. Damage accumulated most rapidly under square waveforms with a high energy requirement. A ramp waveform was the least damaging of those considered. The loading waveforms strongly influenced the damage accumulation under cyclic loading conditions. Finally, it is concluded that machine behaviour in terms of
