Acoustoelastic modeling and effective moduli of prestressed fractured rocks

This dataset contains experimental measurements, MATLAB scripts, and simulation results supporting the analysis of acoustoelastic and effective medium behavior in prestressed fractured rocks. The central file (0_HD-2-1-20230829-193251-Strength-data.xlsx) provides raw and processed data on P- and S-wave velocities, stress conditions, and derived elastic parameters from laboratory tests. Accompanying MATLAB code allows users to calculate Thomsen-style anisotropy parameters, phase velocities, and stress-dependent moduli using nonlinear acoustoelastic and crack-density models. The dataset also includes output results and figures in compressed form (results.zip), and an optional finite-difference simulation toolkit (RSG-FD.zip) for full waveform modeling in fractured media. This data package is designed to be reusable by researchers in geophysics, rock physics, and applied seismology for validating or extending acoustoelastic theory under varying fluid saturations and stress regimes.

This dataset supports the study of stress-dependent seismic velocity behavior in fractured rocks using acoustoelastic and effective medium theories. It includes experimental data, MATLAB code, and simulation results for computing Thomsen-type anisotropic parameters and phase velocities under varying crack densities and prestress conditions. The study combines theoretical modeling with experimental verification to characterize acoustoelastic signatures in fluid-saturated fractured media. All code files included in this submission are original and developed by the authors. Mentions of “Winkler” and “Liu” refer to referenced models or publications and do not indicate code reuse. Therefore, the code is fully compatible with the CC0 license and is released under that waiver.
