Abstract

The global sensitivity analysis of electromagnetic nondestructive evaluation (ENDE) is dealt with in this work. The goal is to calculate the Sobol’ indices, which quantitatively describe the sensitivity of the output(s) with respect to the input variability of the ENDE model. To reduce the computational burden, a recent surrogate modeling technique, the canonical low-rank approximation is applied. Studies are presented via representative examples from eddy-current and magnetic flux leakage nondestructive evaluation.
