The former focuses on its elastic properties, while the latter focuses on the average deformability of fissured specimens, which could be obtained by analyzing the axial stress–strain curve, as shown in Figure 6 b, with the increase in α, E, and E 50 of the fissured specimens generally showing a slightly increasing trend.
