Data and code for "Cross-spectral Control of Normal Contact and Closure in Partially Matched Rough Fractures "

This record contains the data and code underlying the figures of the manuscript “Cross-spectral Control of Normal Contact and Closure in Partially Matched Rough Fractures” (Li, Wei, Wang, and Xu). It includes the Abaqus/Explicit force, displacement, contact-area and gap-volume histories of the direct rough–rough (RR) models, the aperture-based rough–flat (RF) surrogate models and the frictional RR models for 13 partially matched self-affine surface pairs; the nodal contact-pressure fields of all output frames; the upper-, lower- and aperture-surface power spectral densities; the loading-rate, mesh-refinement and frictional validation runs; representative Abaqus input files; and the MATLAB scripts used to generate the surfaces, post-process the simulations and plot the figures.
