Statement

Double torsion samples were fabricated from 6 different shales and one sandstone. Samples were fabricated in 3 different directions relative to the sedimentary layering. Average sample dimensions were 20 mm x 60 mm x 3 mm. In total 66 double-torsion experiments were performed over the beam time. A double torsion apparatus was mounted on to the tomographic stage in the I12 beamline. Two high speed video cameras were also mounted at about 20° either side of the X-Ray beam looking at the sample surface. Double-torsion experiments were conducted following the method described by Becker et al (2011). The method and results are described in detail by Chandler et al, (2018,submitted) "Correlative optical and X-ray imaging of strain evolution during Double Torsion Fracture Toughness measurements in shale"
