This dataset supports the publication:
Van Blitterswyk, J., Fletcher, L., & Pierron, F. (2020). Investigation of the 2D assumption in the image-based inertial impact (IBII) test. Strain. https://doi.org/10.1111/str.12369

This dataset contains:

a) The folder for each specimen contains: raw grid images, videos of full-field displacement, strain, acceleration and strain rate, and fracture diagnostics for the follow-up experiments. 
b) Back-to-back test specimens include raw grid images, and a video comparing strain and acceleration made on front and back surfaces.
c) MATLAB processing codes - experimental images and image deformation
d) MATLAB figures for Figs. X-Y in the manuscript.

Notes: 
Back-to-back experiments: test specimens referred to as BTB_Specimen_#
Follow-up experiments: test specimens referred to as Specimen_R#

The MATLAB codes are described as follows:
IBIITest_ProcessingToolBox_v2_3_BackToBack.zip: Code for processing experimental grid images and performing coordinate system transformation to compare front and back measurements
ImageDeformation_MultiCore: Code for performing image deformation sweeps - designed to run on multiple cores, the number of which can be specified by the user 

The figures are as follows:

Fig. 7a,b - Simulated (a) systematic and (b) random error of E33 identification for 1-3 plane specimen, 0.3 mm grid, 6 pixels/period sampling
