Overview

Analysis reveals that fiber Bragg grating technology detects shear-stress and crack-propagation in pre-cracked sandstone, indicating its potential to mitigate geotechnical hazards.

Key Points

  • Monitoring with fiber Bragg gratings identified key stress variations during crack-propagation.
  • During testing, a maximum shear strain of 6.45% and tensile strain of 1.01% were observed.
  • Assessment using digital image correlation and acoustic emission explored the internal fracture evolution.
  • The findings support fiber Bragg grating applications in understanding geotechnical failure processes.
