GRL 2025 Data

The data files generated by PIVlab [17], along with the MATLAB scripts used to post-process them [18], are available on GitHub: Yaniv-Edery\GRL-2025, repository, while data is archived on Zenodo at: 10.5281/zenodo.15162110. The initial PIV analysis was performed using PIVlab 3.09 [16], an open-source MATLAB-based tool accessible at https://github.com/Shrediquette/ PIVlab. MATLAB R2022b was used for both the PIVlab and the post-processing scripts. For each experiment (’S1’,’S2’,’S3’) we provide three datasets which are used for three different post-processing scripts: • ’Workspace strain stress updated’ includes the measured injection pressure (’P new’ [Pa]), the measured discharge (’Q new’ [cm3/s]) and the displacements in x1 and x2 (’u original’ and ’v original’ [m], respectively ), which where calculated by the PIVlab with a reference frame at P = 0.15M P a. The displacement fields are provided in a temporal resolution of 0.1 s. This workspace is used with the script named ’Code strain stress’ for calculating the averaged strain-stress curve and the strains along x1 (figure 2 ’a’ and ’b’, respectively). Within this script you can also find a section that plots the fluid flux versus P and calculates the maximum Reynolds number throughout the experiment. • ’Workspace 5 sec window updated’ includes the displacements in x1 and x2 (’u original’ and ’v original’ [m], respectively), which where calculated by the PIVlab with a reference frame at P = 0.15M P a. In this dataset we provide the displacements in a temporal resolution of 0.01 s. Yet, this dataset include only 5 s of the experiment, around the localization. This workspace is used with the script named ’Code 5 sec window’ for calculating the 5 s window curve in figure 3 ’a’. • ’Workspace pre localization ref updated’ includes the displacements in x1 and x2 (’u original’ and ’v original’ [m], respectively), which where calculated by the PIVlab with the reference frame being the last frame before the onset of the localization, at a temporal resolution of 0.01 s, and along 3 s of the localization process. This workspace is used with the script named ’Code pre localization ref’, for calculating 2D displacement gradient fields (figure 3 ’b’ and figure 2 in the supplementary material) as well as 2D displacement fields at the onset of localization (figure 1 in the supplementary material).
