PIV data for the six sandbox models

Description

The dataset include the 2D PIV data, specifically horizontal velocity differences, vertical velocity differences, and vorticity differences, plotted in Figures 13-14. Also included are PIV velocity and vorticity maps of Figures S1-S6.

Steps to reproduce

1) design experiments considering analogous materials and scaling parameters; 2)build the experimental models with quartz sand and silicene polymer were deposited according to the experimental preset; 3) monitor the deformation processes using a camera and a particle image velocimetry. Then process the PIV data as images in Tectplot software.
