摘要

This article designed two differential cyclic loading (DCL) modes, each considering the combinations of five groups of different loading and unloading rates. Namely, Mode a: transition from fast-loading-slow-unloading to slow-loading-fast-unloading. Mode b: transition from slow-loading-fast-unloading to fast-loading-slow-unloading. The rock samples tested are slate with five different bedding angles (0°, 30°, 45°, 60°, 90°). The testing results indicate that the two DCL modes with opposite loading sequences can yield different characteristics of energy dissipation. The Mode a which varies fast-loading-slow-unloading to slow-loading-fast-unloading exhibits a sharper decline in normalized dissipated energy and simultaneously holds a smaller residual axial strain rate when compared with Mode b. The impact of loading/unloading rates on magnitudes of phase shift is independent of the applied DCL sequences.
