Figure 7
Fracture evolution under the uniaxial compression experiment and simulation: (a) The failure phenomenon of andesite samples during the laboratory test [25]. (b) The failure phenomenon of the numerical sample of amygdaloidal basalt; green = tensile crack and red = shear crack. (c) AE evolution. (d) AE events’ energy, Me, measured based on the kinetic energy of the AE sources.
