Data for: EFFECT OF MICROSTRUCTURE ON HYDRIC STRAIN IN CLAY ROCK: A QUANTITATIVE COMPARISON

The raw data set provides the optical images of a Tournemire clay rock sample subjected to a desaturation loading. The images are given for the first desaturation path, studied in the paper. The resolution is 2.2µm/pixel. The reference image is the image n°4047, when all desiccation cracks are closed at this stage.
