It was also observed that for tests conducted under load-controlled environment, the irreversible strain evolution was more systematic whereas for tests performed under displacement-controlled environment dissipated energy was a better indicator of fatigue damage evolution.Ĭerfontaine B, Collin F (2018) Cyclic and fatigue behaviour of rock materials: review, interpretation and research perspectives. It is observed that irreversible strain and dissipated energy modelled the fatigue damage evolution in better way as compared to modulus. Applicability of inverted S-curve model to represent the damage evolution was evaluated. Damage evolution of these rocks was discussed in the form of modulus, irreversible strain, and dissipated energy. The Shivpuri sandstone was tested under low confining pressure conditions adopting the similar incremental loading scheme but under displacement-controlled environment. Load was applied through load control mode and four different loading rates were employed. The Garhwal gneiss specimens were studied under uniaxial cyclic loading by adopting incremental loading scheme. In the present study, damage evolution of two natural rocks namely Garhwal gneiss and Shivpuri sandstone from India has been studied through laboratory tests. Each cycle of load causes fatigue damage which accumulates with increasing cycles. Many civil, mining and transportation structures located in rocks are subjected to repeated loading and unloading cycles.
