THE DELETERIOUS EFFECT OF COMPRESSIVE STRESS ON MAGNETIC PROPERTIES OF UNCOATED ELECTRICAL STEEL

Following will be present the the Process data (PD) and the Mean data (MD).
The PD correspond to the data exported directly from the NI-USB6259 and NI-9237 and process after. Since the tests were performed in triplicate, there are 3 folders (B, C and D). Inside these folders, there are files with .opju and .xlsx.
- The first one can be opened with Origin software and corresponds to the hysteresis loops at 1.7 T and 60 Hz. It is important to observe the name of the file. For exemple:

File: B - 2 MPa.opju: Contains the hysteresis loops of test named "B" at 2 MPa;
File: B - 10 MPa.opju: Contains the hysteresis loops of test named "B" at 10 MPa;
File: C - 10 MPa.opju: Contains the hysteresis loops of test named "C" at 10 MPa;
File: D - 10 MPa.opju: Contains the hysteresis loops of test named "D" at 10 MPa;

- The second file can be open with Excell software and contains the magnetic properties of hysteresis loops (coercive field, remanence, power loss) and the magnetostriction values (peak-to-peak magnetostriction).
In a similar way to the .opju, the file names will show the compressive stress.

The MD correspond to the mean value of the triplicate tests and is composed by two .xlsx files:

- "Hysteresis loops for several compressive stresses.xlsx = This files has the mean values of experimental data of the hysteresis loops for several compressive stresses.
-"Magnetic properties for several compressive stresses.xlsx = This files has the mean values of the experimental data of the coercive field, remanence, power loss and peak-to-peak magnetostriction for several compressive stresses.
