Nonlinear simulation of a nondestructive testing measurement system
چکیده انگلیسی

A nondestructive testing (NDT) equipment has been fabricated. The description of the measurement set-up with some measured crack signals applying a Hall-type sensor, furthermore, the T,ΨT,Ψ–ΨΨ potential formulation of the nonlinear eddy current field problem in the time domain can be found in this paper. The hysteresis characteristic of the material has been simulated by the previously developed neural network (NN) based isotropic vector hysteresis model. The nonlinear system of equations has been solved by the fixed-point iteration scheme via the polarization method. Comparisons between the results of the 3D simulations and the measurements are also presented.
