This dataset is related to the publication: "Statistical evaluation of the mechanical and flux trapping properties of standard and thin-wall EuBCO(Ag) bulk superconductors"
The dataset contains the following data: "Raw_data.xlsx" and "Determination_Weibull_modulus.xlsx"
The data can be opened in Microsoft Excel (.xlsx)
The file "Raw_data.xlsx" contains the raw data used to create the plots shown in figures 3, 4 and 6.
Figure 3: Sample number, symple type and trapped field [T] measured for 11 YBCO, 19 EuBCO(Ag) and 20 thin-wall EuBCO(Ag) bulk superconductors.
"Figure_3_YBCO", "Figure_3_EuBCO(Ag)" and "Figure_3_thin-wall_EuBCO(Ag)": X [mm] and Y [mm] give the position of the measurment and B [T] gives the trapped field measured 1.5-2.0 mm above position (x/y) for YBCO, EuBCO(Ag) and thin-wall EuBCO(Ag) bulk superconductors.
Figure 4: Sample number, symple type and tensile strength [MPa] measured for 10 EuBCO(Ag), 10 thin-wall EuBCO(Ag) and 5 Stycast filled thin-wall EuBCO(Ag) bulk materials.
"Figure_4_EuBCO(Ag)", "Figure_4_thin-wall_EuBCO(Ag)" and "Figure_4_filled_EuBCO(Ag)": The bulk materials were compressed in an Instron 5584 and the distance between two marking tapes was measured using a laser to determine failure load [kN] and displacement [mm].
The tensile strength can be calculated from the failure load using Equation 3 (D = 27 mm, t = 10 mm).
Figure 6: Temperature, applied field and trapped field of two EuBCO(Ag) and two thin-wall EuBCO(Ag) bulk materials invetsiagted in the ICE magnet. The fracture fields are marked in red.
"Figure_6_EuBCO(Ag)_1", "Figure_6_EuBCO(Ag)_2" and "Figure_6_thin-wall_EuBCO(Ag)_1": Applied field [T] and trapped field [T] measured at various positions (H1-H11) on the top surface of the EuBCO(Ag) and thin-wall EuBCO(Ag) bulk superconductors.
“Determination_Weibull_modulus.xlsx”: For the determination of the Weibull modulus from the tensile strength of EuBCO(Ag), thin-wall EuBCO(Ag) and Stycast filled thin-wall EuBCO(Ag) bulk materials. The samples were ranked starting with 1 for the lowest tensile
strength. The probability F was calculated using F = (rank-0.5)/(number of samples). Subsequently, ln(tensile strength) vs ln(-ln(1/(1-F))) was plotted. A linear function was fitted to the resulting data points. The slope of the fitted function is the Weibull modulus.
