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