Experimental study on Felicity effect of acoustic emission in rock under cyclic loading and tiered cyclic loading
By using MTS815 equipment and 12 CHs PCI-2 acoustic emission acquisition systemthe acoustic emission(AE) characteristics of rock under tiered cyclic loading and cyclic loading during complete failure process under uniaxial compression were studiedand the Kaiser effect and the Felicity
effect and the standard of acoustic emission increasing obviously on Felicity effect were discussedThe results show that:the existence of Kaiser effect is validbut it is bound and the upper limit of stress level under which Kaiser effect exists is 70% of the peak stressafter thatmemory characteristic
of rock stress shows obvious Felicity effectthe Felicity ratio presents distinct characteristics of 3 stages and decreases in generalthere is no impact on the evolutionary trend of Felicity ratio as long as the standard of obvious acoustic emission falls in a appropriate range.
