Statistical constitutive model for rock damage under uniaxial compression and its experimental study

Based on the strain strength theory and the random statistical distribution hypothesis of rock strength, a statistical constitutive model for rock damage under uniaxial compression, which can reflect the residual strength of rocks, is established by use of the damage constitutive theory of continuous medium. With the servo-testing machine, uniaxial compressive tests are performed on the marble rock, and the parameters of the damage statistical constitutive model are determined according to the experimental results. Comparative analysis shows that the theoretical result is in good agreement with the data from experiments.
