The research aims to analyze how freeze-thaw cycles affect the mechanical properties and damage mechanics of green sandstone.
Conducted experimental tests on sandy rock samples using nuclear magnetic resonance and acoustic emission monitoring.
Analyzed the effects of −30 °C to 30 °C freeze-thaw cycles combined with mechanical loading.
Developed a damage model that identifies three stages of damage evolution.
Identified 30 freeze-thaw cycles as a critical threshold for transitioning from brittle to plastic failure.
Observed significant deterioration in strength and structural stability with increased freeze-thaw cycles.
Characterized the evolution of damage into three distinct phases: quiescence, acceleration, and stabilization.
