Dataset for "Falling through the cracks: energy storage along segmented brittle crack fronts"

README Data repository for "Falling through the cracks: energy storage along segmented brittle crack fronts. Xinyue Wei, and John M. Kolinski (2026)." Dataset DOI: 10.5281/zenodo.18699825 This repository contains data.zip and Supplemental_movies.zip as supporting materials for the manuscript. data.zip contains datasets for cracks from independent experiments labeled as "crack000" to "crack016" in separate folders, and two summarized data files for the crack ligament information and the mean cohesive traction separation measurement. Each crack folder contains crack surfaces, crack tips, processed fields, and crack ligament data used in the analysis. ----------------------------------------------------------------------------------------------Files in supplemental_movies.zip----------------------------------------------------------------------------------------------SupplementalMovie1.avi: A rotational view of the 3D geometry of a stepped crack with material ligament.SupplementalMovie2.avi": An example of the particle trajectory during the opening of a crack. ----------------------------------------------------------------------------------------------Files in data.zip---------------------------------------------------------------------------------------------- |Summary files|----------------------------------|----------------------------------------------------------|Gc_Elig.csv. | Summary of Gc and ligament information for every crack.|cohesive_traction_separation.csv | Data for the mean normalized traction-separation data.|cohesive_deltap_sigmamax.csv | Peak cohesive stress and opening for each crack. |Files per crack folder |---------------------------|----------------------------------------------------------------| surface_curr.csv | Crack surface in the current (deformed) configuration. | surface_ref.csv | Crack surface mapped back to the reference configuration. | cracktip_curr.csv | Crack front curve in the current configuration. | cracktip_ref.csv | Crack front curve mapped back to the reference configuration. | F.csv | Deformation gradient tensor F at each particle. | RU.csv | Principal stretch and rotation from polar decomposition of F. | stress.csv | Cauchy stress tensor. | W.csv | Strain energy density. | Gc.csv | Critical strain energy release rate at every z slice. | cohesive_stress.csv | Cohesive traction–separation data. | lig_particle_indices.csv | Ligament particle indices (single-ligament cases).| lig1_particle_indices.csv | Ligament particle indices for ligament 1 (dual-ligament cases). | lig2_particle_indices.csv | Ligament particle indices for ligament 1 (dual-ligament cases). *Units are stated in individual CSV headers ---------------------------------------------------------------------------------------------Data License--------------------------------------------------------------------------------------------- © 2026 Xinyue Wei, and John M.
