Area of Science:

  • Materials Science
  • Structural Health Monitoring
  • Acoustics

Background:

  • Anisotropic materials are vital for structural applications, necessitating precise damage localization.
  • Current acoustic source localization (ASL) methods face limitations with anisotropic plates, including wave propagation assumptions and prior knowledge requirements.

Purpose of the Study:

  • To develop an advanced ASL method for highly anisotropic plates, overcoming limitations of existing techniques.
  • To enhance localization accuracy for structural assessment and maintenance using a novel sensor configuration.

Main Methods:

  • Proposed an ASL method utilizing three L-shaped sensor clusters (TLSSC) for anisotropic plates with rhombus-shaped wavefronts.
  • Validated the method through experiments on a composite plate using linear ultrasonics for passive acoustic emission detection.
  • Simulated Lamb wave propagation in an anisotropic silicon wafer for active microcrack detection via nonlinear ultrasonics.

Main Results:

  • The TLSSC method significantly improved localization accuracy compared to LSSC-based ASL.
  • Achieved absolute localization errors below 6 mm on a 500 mm x 500 mm plate and relative errors under 5% for both experimental and simulated scenarios.
  • Demonstrated effectiveness for both passive acoustic emission detection and active microcrack detection.

Conclusions:

  • The proposed TLSSC method offers a highly accurate and effective solution for acoustic source localization in anisotropic materials.
  • The method is versatile, applicable to both passive acoustic emission and active microcrack detection through appropriate ultrasonic techniques.
  • This advancement contributes to improved structural health monitoring and maintenance strategies for critical infrastructure.
