Macro-micro fracture characteristics and mechanical response mechanisms of grouted fractured sandstone under uniaxial cyclic loading

Key Points

• Fracture characteristics significantly influence mechanical response under uniaxial loading, demonstrating material resilience.
• Key observations highlight that grouted sandstone exhibits complex fracture patterns during cyclic loading.
• Assessment across various loading cycles shows that the mechanical response varies with changing fracture characteristics.
• Research highlights the need for further studies to understand the implications of mechanical responses in real-world applications.
