Mechanical behaviour of medium-grained sandstones exposed to differential cyclic loading with distinct loading and unloading rates
文献摘要：
This work aims to investigate the mechanical behaviour of medium-grained sandstones under cyclic loading with different loading/unloading rates.This type of cyclic loading is called differential cyclic loading(DCL)and is considered for testing rock behaviour.In the experiments,constant amplitude and multi-level cyclic loadings were performed.Three loading modes were designed to consider different relationships between loading and unloading rates.Axial strain evolution and energy dissipation were analysed for different loading/unloading rates and maximum cyclic load level.The correlations between P-wave velocities and strengths of rocks deduced from this research are compared with existing pub-lished data.The relationships between final strength and axial strain at failure under different loading patterns were also discussed and a rough assessment of the remaining fatigue life is introduced using the predicted value by fitting the axial peak strain.
