True Triaxial Rock Deformation Experiments on Sandstone and Basalt

Raw data from True Triaxial rock deformation experiments on Crab Orchard sandstone and Etna basalt samples. The data includes time series of loads, displacement, and confining pressure, alongside permeability measurements for three loading axes and acoustic emission data. The dataset is provided by the Government Digital Service.

Use Cases

• Modeling rock permeability evolution based on triaxial stress data.
• Analyzing acoustic emission patterns to predict rock failure.
• Calibrating constitutive models for sandstone and basalt using load-displacement time series.
• Studying anisotropic permeability changes under true triaxial loading.

Strengths

• Includes raw time-series data for loads, displacement, and confining pressure.
• Contains permeability measurements for three distinct loading axes.
• Provides separate acoustic emission data.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
