Brazilian Disc Tensile Strength (BDTS) data of tests conducted on salt samples from the Northwich Halite Member

The dataset contains indirect tensile strength data of salt samples collected from the Northwich Halite Member at the Winsford Mine in Cheshire, UK. Each sample was unconfined and deformed under uniaxial compression, where the primary principal stress corresponds to the axial stress and the intermediate and minimum principal stresses are equal to 0. Each sample was deformed using a constant loading rate of 200 N/s. The tests were completed using a servo-controlled stiff load frame equipped with an indirect tension fixture in the Rock Mechanics and Physics Laboratory at the British Geological Survey, Keyworth UK. The data are separated into individual Microsoft Excel files, with each file representing a single test. Each file contains time, axial force, axial displacement, and tensile stress data.

Statement: The samples were unconfined and subjected to uniaxial compression using a servo-controlled stiff load frame equipped with an indirect tension fixture at the Rock Mechanics and Physics Laboratory, British Geological Survey, Keyworth, UK. Each test was conducted under a constant loading rate of 200 N/s until sample failure. The samples, prepared as right circular discs, were positioned between steel curved loading jaws to ensure uniform stress distribution and promote tensile failure at the sample centre. Load cell calibrations were performed annually by an ISO-accredited service provider to ensure measurement accuracy. Tensile strength was calculated using the peak load and sample dimensions according to standard ISRM methods. A separate summary file details the key mechanical properties and experimental parameters for all tests.
