      abstract     = {Assessment of mechanical properties of glass/metal joints
                      is a challenging process, especially when the application
                      relevant conditions of the joints have to be considered in
                      the test design. In this study, a finite element method
                      (FEM) is implemented to analyze a torsional shear strength
                      test designed for glass-ceramic/steel joints aiming towards
                      solid oxide fuel/electrolysis cells application. Deviations
                      from axial symmetry of the square flanges (ends) of
                      respective hourglass-shaped specimens and also supporting
                      and loading sockets of the test set-up are included in the
                      model to simulate conditions close to reality. Undesirable
                      tensile stress and also shear stress concentration appear at
                      the outer edge of glass-ceramic layers, which are less for
                      the hollow-full specimen. The simulation results show that
                      for a specimen with either 9 mm thick square- or 6 mm
                      thick triangular-flanges, locally enhanced tensile stresses
                      almost disappear, resulting in a symmetric shear stress
                      distribution. The difference between the analytically
                      derived nominal shear strength and the real critical shear
                      stress derived via simulation reduces with decreasing the
                      fracture torque.},
