“…The relation between the resistance variation and the electrical conductivity of the tested material depends on the eddy currents distribution in the latter, which can be obtained by numerical modeling [8]. Four parameters can be used to characterize the CFPR ply anisotropic conductivity.…”

“…The whole system is characterized by the vacuum magnetic permeability (µ 0 ). To avoid the modeling at the filament scale, a homogenized nonlinear electrical conductivity tensor is defined for the sample, given by (1), where σ // and σ T denote the conductivities parallel and transverse to the filaments [2][3][4].…”

“…Numerical modeling is then often necessary [1,2], where the conventional numerical tools have difficulties to provide accurate solutions in reasonable computing times due to multiscale dimensions, nonlinearities and high anisotropies. In these cases, specific modeling approaches meeting a better compromise between accuracy and computing time are needed.…”

“…In these cases, specific modeling approaches meeting a better compromise between accuracy and computing time are needed. In previous works, we have developed an electromagnetic model, based on an integro-differential formulation, for a rapid eddy current computation in carbon fiber reinforced composite polymers for nondestructive testing (NDT) applications [2]. In this work, this model is extended to model eddy current losses in multifilamentary HTS composite tapes submitted to external sinusoidal time varying magnetic fields.…”

Abstract:In this work, a numerical model is developed for a rapid computation of eddy currents in composite materials, adaptable for both carbon fiber reinforced polymers (CFRPs) for NDT applications and multifilamentary high temperature superconductive (HTS) tapes for AC loss evaluation. The proposed model is based on an integrodifferential formulation in terms of the electric vector potential in the frequency domain. The high anisotropy and the nonlinearity of the considered materials are easily handled in the frequency domain.

“…Among various NDT methods [10][11][12][13][14], ECT is advantageous because of its easy operation, single-side detection, low requirement of surface preparation, and applicability in harsh environment, as well as other properties [15]. Hence ECT has taken an increasing interest in the detection and characterization of defects in CFRP recently [16][17][18].…”

The paper studies the characteristics of eddy current (EC) distribution in carbon fiber reinforced polymer (CFRP) laminates so as to guide the research and operation of eddy current testing of CFRP. To this end, an electromagnetic field computation model of EC response to CFRP based on the finite element method is developed. Quantitative analysis of EC distribution in plies of unidirectional CFRP reveals that EC changes slowly along the fiber direction due to the strong electrical anisotropy of the material. Variation of EC in plies of multidirectional CFRP is fast in both directions. The attenuation of EC in the normal direction in unidirectional CFRP is faster than that in isotropic material due to faster diffusion of EC. In multidirectional CFRP, EC increases near the interfaces of plies having different fiber orientations. The simulation results are beneficial to optimizing sensor design and testing parameters, as well as damage detection and evaluation.
