Fatigue failure characteristics of some models of jointed rock

Fatigue properties of intact sandstone samples subjected to dynamic uniaxial cyclical loading

“…Brown and Hudson [17] studied the fatigue characteristics of idealized models of jointed rocks under cyclical uniaxial loading. These test results showed that the intact and the failed models of jointed rock were extremely susceptible to cyclic fatigue failure and the residual strength locus interpretation of time-dependent failure of rock was explained.…”

“…From the reported literature, it was found that intact [3][4][5][6][7][8][9][10][11][12][13][14][15][16] and failed models of jointed rock [17][18][19][20] were extremely susceptible to cyclic fatigue failure. Some have also studied the dynamic damage properties of nonjointed intact samples [21][22][23][24][25].…”

Crack Initiation, Propagation, and Failure Characteristics of Jointed Rock or Rock‐Like Specimens: A Review

“…e dynamic response of jointed rocks will be different from their static properties, and the mechanical behavior of jointed rock mass has also been investigated by scholars. e previous studies [140][141][142] reported that jointed rock mass are very sensitive to the cyclic loading and the joint confirmation has a significant influence on the dynamic strength and deformation behavior. Erarslan and Williams [143] conducted the static and cyclic loading test on inclined cracked chevron notched Brazilian disc (CCNBD) specimens, and the experimental results show that the failure load obtained through cyclic loading decreased between 30 and 45% compared with those in static loading.…”

Fatigue properties analysis of cracked rock based on fracture evolution process

“…Obviously, deformation development under cyclic loading is similar to the creep test. So, the axial irreversible deformation can be divided into three stages: initial deformation, constant deformation rate and accelerative deformation using the creep concept [2,4] . …”

“…HAIMSON and KIM [3] , BROWN and HUDSON [4] earlier pointed out that the fatigue failure curve is controlled by complete force−displacement curve under static loading and is equal to that of post-peak corresponding to the maximal cyclic load. Then, GE et al [6−7] proposed that the fatigue damage of intact rock has a threshold value and the fatigue failure is controlled by cumulative deformation.…”
