Updated description of Crack propagation in weak snowpack layers: Insights from high-speed photography from
This data set includes material and results described in the related research article: Bergfeld, B., van Herwijnen, A., Reuter, B., Bobillier, G., Dual, J., and Schweizer, J.: Dynamic crack propagation in weak snowpack layers: Insights from high-resolution, high-speed photography, The Cryosphere Discuss. [preprint], https://doi.org/10.5194/tc-2020-360, in review, 2021. # Context: In order to study 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 for related publication - Ilustrative videos showing crack propagation - High-speed recordings of the Experiments (the raw .cine files are available upon request) Processed Data containing: - displacement, velocity and acceleration fields for the three PSTs - speed and touchdown dataset
