Triaxial compressive strength data of tests conducted at varying strain rates and confining pressures on salt samples from the Northwich Halite Member
The dataset contains triaxial compressive strength data of salt samples collected from the Northwich Halite Member at the Winsford Mine in Cheshire, UK. Each sample was subjected to varying strain or displacement-equivalent rates under conventional triaxial stress conditions to evaluate its mechanical response to different loading conditions. The experiments were conducted over two testing campaigns between July 2022 and August 2023, using a servo-controlled stiff load frame in the Rock Mechanics and Physics Laboratory at the British Geological Survey, Keyworth, UK. The dataset is organized into individual Microsoft Excel files, each corresponding to a single test and containing parameters such as time, force, stress, displacement, and strain. A summary file detailing sample characteristics and test conditions is also included.

- Statement
- Each sample was subjected to triaxial stress conditions, where the primary principal stress corresponded to the axial stress and the intermediate and minimum principal stresses are equal to the confining pressure. The experiments followed a three-stage process: (1) hydrostatic loading to a pre-determined confining pressure (5–45 MPa), (2) active deformation under either a constant strain rate (ranging from 1e-5 to 1e-3 per second) or a constant displacement rate (0.0012–0.12 mm/s), and (3) stress unloading. The confining pressure remained constant throughout each test, while temperature and humidity were maintained at room conditions. Measurements were recorded at a rate of 4 Hz in time domain and at every 250 N in force domain to capture force variations accurately. An axial displacement correction was applied using a 5th-order polynomial to obtain a true measure of sample displacement.
