The distributed point source method (DPSM) now models ultrasonic fields in fluid-solid interfaces, outperforming older methods. This advanced technique accurately captures complex phenomena like leaky Rayleigh waves.

Area of Science:

  • Acoustics
  • Materials Science
  • Non-Destructive Evaluation (NDE)

Background:

  • The Distributed Point Source Method (DPSM) is a semi-analytical technique for modeling ultrasonic fields.
  • Existing DPSM models have been applied to homogeneous and multi-layered fluid structures.
  • There is a need for advanced modeling techniques capable of handling complex interfaces and non-homogeneous materials.

Purpose of the Study:

  • To extend the DPSM for modeling ultrasonic fields in both fluid and solid media near a fluid-solid interface.
  • To develop and validate a matrix inversion-based DPSM technique.
  • To accurately model ultrasonic phenomena involving leaky Rayleigh waves at critical angles.

Main Methods:

  • Development of a novel matrix inversion-based Distributed Point Source Method (DPSM) technique.
