Dataset in support of the journal article 'Fracture and relaxation in dense cornstarch suspensions'

Abstract

This dataset contains three sections: Analyzed Data, Code and X-Ray Data. Analyzed Data: data plotted in figures 1 to 5 - data_figure_1b.xlsx: volume and time for the three experiments shown in Figure 1b - data_figure_1c.xlsx: gauge pressure, hydrostatic pressure, mass fraction, volume rate and confidence intervals as shown in Figure 1c - data_figure_2c.xlsx: equivalent radius R and centroid height Z for the experiments shown in Figure 2c - data_figure_2d.xlsx: mass fraction, gauge pressure, effective viscosity, equivalent radius, centroid height, vertical velocity, growth velocity, Vb/Vg and dZ/dR as shown in Figure 2d - data_figure_3c.xlsx: gradient intensity and probability (fraction) of gradient intensity for the experiments shown in Figure 3c - data_figure_3c_inset.xlsx: mass fraction and metric for local fracture characterization as shown in the inset of Figure 3c - data_figure_4b_4c.xlsx: time, volume, equivalent radius, shear rate from growth and metric for local fracture characterization for the experiment shown in Figure 4b and c - data_figure_4d.xlsx: mass fraction, gauge pressure, critical shear rate from rheology, time for relaxation and error, time for critical shear rate and error as shown in Figure 4d - data_figure_5.xlsx: stress, shear rate and viscosity for the 57% and 58% mass fraction rheology data shown in Figure 5 Code: functions to calculate air thickness and gradient from X-ray data - intensityToThickness.m: MATLAB function to calculate the air thickness in mm from the X-ray intensity recorded in the X-Ray Data section - calculateGradient.m: MATLAB function to calculate the air thickness gradient intensity from the air thickness data X-Ray data: Full X-ray data for experiments shown in figures 1 to 4 - figure_XX_phimYYpc_PgZZkPa: XX figure number, YY cornstarch mass fraction in percent, ZZ gauge pressure in kPa Scale is 0.112 mm/px for the 1000x1000 data and 0.056 mm/px for the 2000x2000 data. Load the data and use intensityToThickness.m to convert to air thickness data.
