Analysis of Uniaxial Fatigue Mechanical Properties and Constitutive Modeling for Freeze–Thaw Cycled Red Sandstone with Double Fissures
This study addresses the challenge of the mechanical behavior of fractured rock masses in cold regions under freeze–thaw-fatigue coupling. Uniaxial step-incremental cyclic loading tests were conducted on double-cracked red sandstone subjected to different numbers of freeze–thaw cycles to reveal the damage evolution law...
