Study on the Fractional‐Order Creep Constitutive Model of Rock Considering Chemical–Stress–Seepage Damage
Accurate characterization of rock creep under coupled chemical–stress–seepage conditions is essential for deep rock stability. A three‐dimensional fractional‐order creep constitutive model is developed. Chemical, stress, and seepage damage are quantified by elastic modulus degradation, the Kachanov evolution, and p...
