Innovative Eddy Current ProbesCharacterization Of Micro Defects

This paper deals with an adaptive mesh refinement method applied to 3D eddy current non-destructive testing computations by finite element method. The principle of Ligurian is used

The kriging approximation is built using a random process model of the simulator and a set of simulation results obtained for a number of different input configurations.. The

Analysis of the data showed that the sensor output was in relation with different parameter of powder (diameter, density and structural) that the sensitivity of the sensor

Electromagnetic and magnetic characterizations of the powders was investigated by eddy current and vibrating sample magnetometer, the impedance, the coercivity and

In the present study, we formed FeCoAl based alloys by MA and investigated their magnetic properties; especially the eddy current dependence at low frequency and the coefficient of

The simulation results obtained using the finite element method are presented in the first part using a traditional probe based on classical winding coils, in the

Experimental results show that fine nanocrystalline alloy powders prepared by mechanical milling are very promising for microwave applications and it is suggested that Eddy
