“…Several studies point out that monotonic stress-strain curves act as a failure locus for cyclically loaded samples (Haimson and Kim 1971;Martin and Chandler 1994;Yamashita et al 1999;Zhang et al 2008;Xiao et al 2009;Guo et al 2012;Song et al 2013;Liu et al 2017). An example of such a phenomenon is reproduced in Fig.…”

“…ere are some studies on the dynamic response characteristics of various types of rock under coupled static-dynamic loading and high-stress conditions [4][5][6][7], and the results have revealed the mechanism of deep rock burst. Song et al [8] carried out cyclic loading tests on salt rock samples and determined the fatigue life of rock salt samples under different upper and lower stresses, cyclic loading speeds, temperatures, and confining pressures. Fan [9] further quantified the fatigue life and deformation evolution characteristics of salt rock by subjecting it to different stress amplitudes.…”

The mechanical response characteristics of sandstone specimens under different stress amplitudes and loading frequencies were tested by a TAW-2000 rock triaxial testing machine. The characteristics of the stress-strain curve and the evolution process of strain damage under cyclic loading are analyzed. Based on creep theory and the disturbance state concept, a theoretical model between the axial compressive strain, axial compressive stress, and cycle number is established. The results show that there exists an upper threshold value of stress in cyclic loading above which the specimen will be damaged. As peak stress increases, the energy loss and irreversible deformation caused by damage gradually increase. When loading to an unstable peak stress under cyclic loading, the fatigue damage of sandstone under cyclic loading undergoes three characteristic stages: the initial stage; the stable stage; and the accelerated failure stage. The parameters of the strain damage model based on the disturbance state concept of sandstone are identified by test data, and the rationality of the model is validated by comparing theoretical values with experimental measurements.

“…To build the relationship between damage value and cyclic number, assume that F � (n/(N f − n)); thus, the fatigue damage value increases from 0 to 1, while n increases from 0 to N f . e fatigue damage model based on the Harris attenuation function can be expressed as follows: Figure 6 shows the results of the salt rock fatigue test conducted by Song et al [22] at real-time temperature. e test temperature was set at 13°C, 30°C, and 60°C, respectively, and the upper and lower limits of fatigue stress are 90% and 20% of the peak stress for each temperature (only the results of T � 30°C in literature [22] are given, due to the limitation of space).…”

“…However, the cycle numbers are limited and the cyclic load is applied after the applied temperature in the aforementioned works, which is different from the rock fatigue damage at real-time temperature. With that in mind, Song et al [22] and Zhao et al [23] carried out fatigue tests on salt rock and granite under real-time temperature, respectively. e test results show that temperature causes fatigue damage and affects the deformability of rock.…”

The deformation rules and failure types of rock fatigue damage at different temperatures are quite different, and existing constitutive theory cannot describe them quantitatively. A novel rock fatigue damage model considering the effects of temperature was presented based on phenomenology. In this model, the residual strain method was used to define the fatigue damage, and the Harris attenuation function was introduced to characterize the cyclic damage evolution. The proposed model has considered the influence of the initial damage and temperature, and the model parameters can be easily calculated. The accuracy of the model was verified by comparing the calculated values of cyclic upper strain and fatigue life with previous test results. The physical significance of the model parameters shows that parameter a is related to fatigue stress ratio and lithology, while parameter b is related to temperature. The study has some reference values for the fatigue damage model of rock considering the influence of temperature.
