Abstract

The article focuses on the application of a coupled circuits method to study the effects of test-piece thickness, lift-off (air gap between sensor and test-piece), and electrical conductivity on the sensor response in pulsed eddy current (PEC) testing of 2D cylindrical and axisymmetric devices. This method, based on mutual inductance calculations and Kirchhoff's laws, solves transient algebraic equations to model the electromagnetic behavior without requiring re-meshing, offering computational efficiency compared to finite element methods. Results demonstrate that variations in thickness, lift-off, and conductivity significantly influence the sensor current response, with findings closely matching finite element computations. The study highlights the method's potential for accurate characterization of geometry and physical properties in nondestructive evaluation applications.
