In order to evaluate the damage evolution of rock under external loading, the surface deformation field of a rectangle marble specimen is inspected and analyzed using digital speckle correlation method (DSCM). Experimental results show that the damage evolution of rock undergoes 3 stages: they are uniformly distributed damage, localized damage and catastrophic failure stage. A statistic indicator, standard deviation of the strain field, can be used to quantitatively express the damage localization level.
