Structural Health Monitoring

Background:

Lamb waves are crucial for non-destructive testing and structural health monitoring (SHM).
Traditional SHM sensors like strain gauges have limitations in coverage and installation.
Optical fiber sensing offers a promising alternative for distributed measurements.

Purpose of the Study:

To investigate the use of a phase-sensitive optical time-domain reflectometry (ϕ-OTDR) sensor for Lamb wave detection.
To evaluate the potential of ϕ-OTDR for structural health monitoring and damage detection.
To explore the integration of distributed strain measurement using Brillouin scattering with Lamb wave sensing.

Main Methods:

Excitation of Lamb waves using a piezoelectric transducer in an aluminum plate.
Detection and analysis of Lamb waves using a ϕ-OTDR system.
Simultaneous distributed strain measurement using Brillouin scattering along the same optical fiber.

Main Results:

The ϕ-OTDR system successfully detected and resolved Lamb waves in distinct regions of the aluminum plate.
Variations in Lamb wave propagation were observed due to changes in plate loading conditions.
The integrated system demonstrated the capability for both Lamb wave detection and distributed strain measurement.

Conclusions:

ϕ-OTDR is a viable technology for Lamb wave detection and SHM applications.
A single optical fiber can be used for both Lamb wave sensing and distributed strain measurements.
This approach offers a potential replacement for conventional SHM sensors, providing multi-point sensing capabilities.
