AE responses, energy evolution, and damage constitutive model of jointed rock-like material subjected to unilaterally confined compression.

Faults, joints, and other weak structural surfaces are commonly present in the surrounding rocks of tunnels and goafs. To investigate the effect of different joint angles on the instability and failure of surrounding rock, joints of varying angles are fabricated using 3D printing technology. Unilateral confined compres...
