Mechanical behavior and acoustic emission characteristics of fissured sandstone under low frequency disturbance

Key Points

• Mechanical behavior significantly alters under low frequency disturbance, indicating potential changes in material integrity.
• Acoustic emission data show specific patterns correlating with stress levels in fissured sandstone, providing insight into fracture dynamics.
• Analysis of fissured sandstone under low frequency disturbances measured critical material properties and failure points.
• Highlights the importance of understanding mechanical and acoustic responses of sandstone in predicting geological shifts.
