The datasets provided are compiled from an experimental campaign investigating the high strain rate properties of soda-lime-silica glass and the effect of residual stresses; see title and DOI of the linked peer-reviewed publication. In total, 315 samples were tested at two loading rates: a quasi-static at 2.0 MPa s-1 and a dynamic at 4.3x106 MPa s-1. A ring-on-ring test configuration for the load application was integrated into a universal testing machine (Instron 8872) and a novel, modified split-Hopkinson pressure bar (SHPB) setup (related publication to the employed SHPB setup is referenced below). From the equibiaxial loading of small circular glass samples, the strength and stiffness (Young's modulus) were determined, using load/strain recordings and deflection measurements with the stereo digital image correlation (Stereo-DIC) technique, respectively. Hence, the following zip-files can be accessed:
Each file includes the individual measurements stored as txt-files with the following sample information in a header: sample name, sample ID, type of loading, load application, failure origin, location of failure origin, sample height, and compressive surface stress. Load-time histories can be reconstructed from the datasets for the quasi-static loading (a). As strains were measured in the high strain rate experiments, the datasets for the dynamic loading (b) provide data from which strain-time histories of the waves recorded in the bar/tube system of the SHPB setup can be reconstructed. Lastly, from the datasets of the performed stereo-DIC deflection measurements (c), load-deflection curves can be reproduced for the ten points extracted for each of the ten samples tested, providing information about the glass' stiffness.
Other data that might be of interest related to the linked publication will be provided upon reasonable request.
