Source Data and MATLAB Plotting Code for “Progressive Fracture Linkage Transforms Distributed Damage Into a Dominant Spanning Cluster”

This dataset contains the source data and MATLAB plotting code for Figures 1–3 of the manuscript “Progressive Fracture Linkage Transforms Distributed Damage Into a Dominant Spanning Cluster.” It includes stage-resolved simulated fracture geometries and cluster labels, selected natural-outcrop fracture maps and cluster labels, realization-level spanning and linkage metrics, classifications of the processes that complete first spanning, and factor-level sensitivity results.

The numerical results comprise 270 realizations, of which 267 reached the standardized postspanning state at (1.25P_{21c}). The included MATLAB function reproduces the three main figures as high-resolution PNG files. The natural-outcrop subset was derived from the publicly available dataset of Zhu (2021), 4TU.ResearchData, DOI: 10.4121/14865096.v2.
