A meso-damage-based constitutive model for yellow sandstone under dry–wet cycles
•The evolution of mesostructural characteristics of sandstone under dry–wet cycles is observed. | |
•The meso-damage deterioration mechanism of sandstone under dry–wet cycles is analyzed. | |
•The damage changes in the whole process of rock deformation and failure are obtained. | |
•The rock damage intrinsic model under the coupling of dry–wet cycles and load is proposed. |
