Critical aircraft structures are susceptible to hidden corrosion. Find-it and fix-it approaches are inefficient as it relates to managing the problems associated with corrosion. More comprehensive corrosion information may be obtained using data fusion from several detection and evaluation methods. To this end, microwave, conventional and pulsed eddy current data from a multi-layer corroded pan...

An expression for the eddy current loss in solid rectangular cores is obtained using linear electromagnetic field analysis. Wherefrom text book formula for eddy current loss is derived highlighting various assumptions involved. To get an insight into the current interruption phenomena, electromagnetic fields in a composite rectangular core are analyzed. It is concluded that the reduction in edd...

It is different to detect defect in multilayer structure of an aging aircraft fuselage, pulsed eddy current (PEC) technique has been demonstrated to be capable of quantifying this defect. Based on theoretical analysis of PEC technique, the array probe is designed and the array PEC imaging technique has been supposed to detect corrosion in the multilayer structure. By selecting peak amplitude an...

The wall-thinning measurement of ferromagnetic plates covered with insulations and claddings is a main challenge in petrochemical power generation industries. Pulsed eddy current testing (PECT) considered as promising method. However, the accuracy limited due to interference factors such lift-off cladding. In this study, by decoupling analytic solution, feature only sensitive plate thickness pr...

Eddy current pulsed thermography (ECPT) is an effective non-destructive testing technique for evaluating the integrity and safe operation of conductive composite components such as carbon fibre reinforced polymer (CFRP) in aerospace applications. However, since any measures a surface thermal distribution, ECPT does not directly provide comprehensive information at layer level, e.g., about orien...

non-destructive eddy current (ec) technique has long been used to detect discontinuities in materials. recently, its application has been extended to characterize materials microstructure. in order to identify different microstructures, four plain carbon steel bars with different chemical compositions (aisi 1015, 1035, 1045 and 1080) were used in annealed condition. the pearlite percentage, car...
