Dependence of the Temperature on the Fatigue Properties of Sandstones Under Graded Cyclic Loading and Unloading of the Intermediate Principal Stress

Key Points

• Fatigue properties are significantly influenced by temperature in sandstone during cyclic loading and unloading phases.
• Key measurements indicate changes in fatigue strength at specified temperature increments, demonstrating a clear dependency relationship.
• Observational analysis investigates the interrelationship of temperature and fatigue properties across diverse loading conditions in sandstone samples.
• Understanding temperature effects on fatigue behavior is crucial for predicting failure in geological and engineering contexts.
