Figure 14
Correlation between initial porosity and volumetric strain for a porous sample tested at 20 MPa of confining pressure: correlation between initial local porosity and volumetric strain for four different steps: (a) step 5, at 7 MPa [see Fig. 12

(c)]; (b) step 12, at 14 MPa (Fig. 13

); (c) step 14, at 16 MPa; (d) step 18, at 20 MPa. The histogram below shows the initial local porosity distribution, for bins with over 100 data points. The linear fit (red line) correlates initial porosity and volumetric strain.
