In damage mechanics, the damage variable, a number within [0 1] is taken to express the degree of degradation of materials.
In the published research works, experimental techniques like scanning electron microscopy (SEM), computed tomography (CT) and acoustic emission (AE) techniques, etc., are used to measure the damage of rock materials [4-6].
