Geomechanical strength data of mudstone samples from the Gunthorpe Member, Sidmouth Mudstone Formation. The British Geological Survey (BGS) conducted tests involving cyclic thermal loading and triaxial compression under controlled pressure and displacement rates. Data are stored in individual Excel files containing time, force, stress, displacement, and strain measurements.
Use Cases
- Modeling rock deformation under thermal stress based on the described heating and loading stages.
- Predicting triaxial compressive strength of mudstones based on stress and strain data.
- Analyzing time-dependent material response based on the constant displacement rate of 0.0012 mm s-1.
- Calibrating geomechanical simulations using the detailed pressure conditions (1-1.4 MPa axial, 0.5-5 MPa confining).
Strengths
- Testing was completed to ISRM specifications, indicating standardized methodology.
- Data includes multiple measurement types per test: time, force, stress, displacement, and strain.
- Each test file documents a complete three-stage process: heating, preloading, and triaxial compression.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and total number of test files are unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to samples from the UK's Sidmouth Mudstone Formation.
