Updated description of Crack propagation in weak snowpack layers: Insights from high-speed photography from
This data set includes the raw material and results described in the research article by Bergfeld et al. (2021). # Context: In order to study the crack propagation in weak snow pack layers in great detail, we recorded Propagation Saw Test (PST) experiments using a high-speed camera and applied digital image correlation (DIC) to derive displacement and strain fields in the slab, weak layer, and substrate. We demonstrated the versatility and accuracy of the DIC method by showing measurements from three PST experiments, resulting in slab fracture, crack arrest and full propagation in the related publication. # Content: - Supplementary material of the publication - High-speed recordings of the Experiments - Ilustrative videos showing crack propagation - Processed Datasets
