Variable-order fractional constitutive model for triaxial fatigue behavior of freeze-thaw double-fractured red sandstone

To explore the fatigue behavior of freeze-thaw fractured rocks, triaxial incremental cyclic loading tests were performed on double-fractured red sandstone under three freeze-thaw cycle conditions. A fatigue deformation constitutive model incorporating variable-order fractional derivatives was propos...
