MODELLING OF FLAW RESPONSES IN EDDY CURRENT TESTING

MODELLING OF FLAW RESPONSES IN EDDY CURRENT TESTING This paper presents the practical configuration for detecting cracks in material, by applying an electromagnetic field along the largest dimension of the crack. An electromagnetic field formulation is proposed using Helmholtz's equation and Biot Savart's law. The system equation is solved by using the finite element method FEM. The exemplary results of calculation eddy currents lines in material and relative resistance versus probe position are presented. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png COMPEL: Theinternational Journal for Computation and Mathematics in Electrical and Electronic Engineering Emerald Publishing

Abstract

This paper presents the practical configuration for detecting cracks in material, by applying an electromagnetic field along the largest dimension of the crack. An electromagnetic field formulation is proposed using Helmholtz's equation and Biot Savart's law. The system equation is solved by using the finite element method FEM. The exemplary results of calculation eddy currents lines in material and relative resistance versus probe position are presented.
