This dataset contains experimental mechanical and imaging data as described in "Modelling the failure precursor mechanism of lamellar fibrous tissues, example of the annulus fibrosus" Mengoni M., Jones A.C. and Wilcox R.K. Journal of the Mechanical Behavior of Biomedical Materials doi: 10.1016/j.jmbbm.2016.06.030 (see related ressources) Samples are detailed in dataSummary.csv (provenance, size, type of test performed, microscopy) Mechanical instron raw data for each sample is in mechanicalTesting.zip DIC microscopy images are present for some samples in an archive file. Python scripts that analyse the experimental data are postProOvineAF.py and postProInstronDataTools.py
