Multiscale Investigation of Rock Damage Evolution Using AE, DIC, and Lattice Spring Modeling

Key Points

• Damage evolution in rocks is tracked using acoustic emission methods, revealing critical patterns in material failure.
• The study analyzes 10 distinct sample conditions, evaluating how various stress distributions affect rock integrity.
• Observational analysis applies digital image correlation and lattice spring modeling to assess micro and macro damage scales.
• These findings may enable improved prediction models for rock stability in geotechnical applications.
