Overview

Investigating a baseline-free method for detecting fatigue cracks, emphasizing temperature effects on detection reliability.

Key Points

  • The baseline-free method detects cracks around 3 mm effectively, enhancing practical monitoring in service conditions.
  • This approach relies on nonlinear parameters which act as sensitive indicators of damage initiation and growth.
  • Temperature variations can significantly affect the method’s performance, indicating a need for compensation strategies.
  • The findings highlight both the advantages and limitations of nonlinear guided wave methods for structural health monitoring.
