Overview

The study introduces a new RMS-based method for detecting cracks in structures, indicating improved reliability and robustness.

Key Points

  • This research aims to develop a robust method for in-service crack detection without relying on baseline data.
  • Introduced RMS value of time-domain signals for crack monitoring
  • Utilized the Dynamic Piecewise Linear method for data analysis
  • Conducted fatigue experiments on multiple specimens
  • RMS changes showed two distinct stages correlating with crack initiation
  • Successfully identified cracks smaller than 2 mm
  • Demonstrated consistent detection across various sensor configurations
