This paper focuses on the PC based instrumentation and software developed for the swept frequency material profiler. Results of the NN based classifacation are summarized, and potential applications discussed.
This paper presents a comparative analysis of three different eddy current testing methods for tube inspection conventional one side eddy current testing, 2) through-transmission eddy current testing, and 3) remote field eddy current testing. The author also studied the results from different arrangements of exciter coil and receiver coil of the eddy current testing method for tube inspection. The author concludes that the remote field eddy current testing is a ...
Numerical models capable of modeling magnetic flux leakage (MFL) methods of nondestructive testing are of significant interest to industry. The nonlinear nature of the MFL problem necessitates the use of an iterative model, thereby resulting in excessive computational effort. This paper describes an approach for developing an equivalent linear model (ELM) where the ferromagnetic region is appropriately partitioned into different domains with each domain being assigned a constant permeability value ...
