Eddy-current probe impedance due to a volumetric flaw
Eddy current induced in a metal by a coil carrying an alternating current may be perturbed by the presence of any macroscopic defects in the material, such as cracks, surface indentations, or inclusions. In eddy-current nondestructive evaluation, defects are commonly sensed by a change of the coil impedance resulting from perturbations in the electromagnetic field. This paper describes theoreti...
متن کاملDimension Estimation of Rectangular Cracks Using Impedance Changes of Eddy Current Probe with Neural Network
Eddy current (EC) nondestructive testing (NDT) based on probe impedance changes in the crack regions is considered in this paper. For this a numerical simulation is introduced for the development of the EC-NDT system using 3D finite element software. This model is used to simulate the rectangular cracks with various dimension and prepares the data required for artificial neural network. The neu...
متن کاملBorescope and Eddy Current Dual Probe for In Situ Detecting Cracks in an Aeroengine Labyrinth Disc
Cracks often arise in an aeroengine labyrinth disc, which endanger flight security. Non-destructive testing (NDT) must been carried out in the labyrinth disc during the aeroengine working time. In situ detecting cracks in the labyrinth disc, the probe need pass through three layers narrow holes of aircraft skin, engine shell and outlet duct. Ultrasonic, radiography and liquid penetrant inspecti...
متن کاملElectrical Impedance Imaging Using Eddy Current
Electric impedance imaging is a method of reconstructing spatial distribution of electrical conductivity inside a subject. In this paper, a new method of electrical impedance imaging using eddy current is proposed. The eddy current distribution in the body depends on the conductivity distribution and the magnetic field pattern. By changing the position of magnetic core, a set of voltage differe...
