Rebars evaluation with magnetic and eddy current method

This data can be opened with Matlab

The data was collected as a part of the project National Science Centre (in Polish: NCN—Narodowe Centrum Nauki), program: Preludium, grant number 2021/41/N/ST7/02728 (“Smart support system for the Magnetic Force Induced Vibration Evaluation (M5)—an electromagnetic, nondestructive method designed for the evaluation of composite materials containing ferromagnetic and conductive elements.”).

The data was used to prepare papers:

FOLDER: MAGNETIC
files:
NN.mat - same pole polarization
NS.mat - opposite pole polarization
NIC.mat - no polarization

waveforms data name:
two first letters - a type of polarization
third-fourth letters - spatial component
last two signs - concrete cover thickness

FOLDER: EDDY CURRENT
Old data, measurements made while preparing a master thesis. The data files were used to compare to the magnetic method. All results were obtained for 26 different thicknesses of concrete cover. At the end of each data file, there is a number showing a number of the measurements; this number is multiplied by two to give concrete cover thickness.
