Figure 3

The loading path and the corresponding complete stress-strain curves for the typical granite samples under dynamic frequency of 0.04, 0.1, 0.5, and 1.0, respectively. (a, c, e, g) Plots of the loading path of the cyclic loading. (b, d, f, g) Plots of the axial, lateral, and volumetric stress-strain curves.
