Abstract
An analysis is conducted of the possibility of making an assessment of active stresses in steel elements of civil engineering structures by measuring three electromagnetic diagnostic signals: the Barkhausen noise (BN), impedance components in in-series LCR circuits and the residual magnetic field (RMF) components. The issues under consideration belong to what is referred to as inverse problems of non-destructive testing. In this case, they consist in using electromagnetic properties for the active stress assessment. In order to develop the relevant correlation, experiments are needed that enable metrologically appropriate measurements, extraction of the diagnostic signal features and analysis of correlations between the features and active stress. The testing takes account of the impact of the element geometry and loading history. Impact factors are determined that need to be taken into consideration while developing quantitative diagnostic correlations. © 2019 Elsevier B.V.
