Data for: Evolution of nonlinear elasticity and crack damage of rock joint under cyclic tension

Figures S1 to S5 present the results of tensile stress-strain curves, the residual strain and also the fracture surfaces after failure of sample LS2, LS3, GA1, GA2, and GA3, respectively. Figure S6 shows the prediction results of strain-dependent crack density model with the comparison with experimental measurements of tensile stress-strain curves. Data set S1 provides the experimental data of tensile stress-strain. LS represents limestone stylolitic joints, and GA indicates granite artificial joints.
