Example measurements plotted against shear strain (%) from drained triaxial shearing tests performed on LBS 1·0–2·0 (test 8, left) and LBS 0·6–1·18 (test 5, right) at an effective confining pressure of 200 kPa and axial displacement rate of 1 mm/h: (a), (b) stress ratio (q/p′); (c), (d) volumetric strain (%) (dilation shown as positive); (e), (f) AE rate (RDC/min); (g), (h) b-value
