... sandstone and Solnhofen limestone. Both are known for their high uniaxial compressive strength > 100 MPa and Young’s modulus > 30 GPa. Six end face geometry categories were tested on cylindrical samples with a diameter of 30 mm and a nominal length of 65 mm: (1) two standard end faces with tolerances...
