      abstract     = {A torsion test recently implemented for solid oxide fuel
                      cell sealant materials is analyzed as a method for measuring
                      the shear strength of sealant for solid oxide fuel cells.
                      The finite element method is used to simulate the stress
                      distribution in the hourglass-shaped steel specimens with
                      intermediate sealant layer with different specimen's
                      dimensions and configurations. Also, it is analyzed how
                      stress concentration changes if the sealant does not
                      completely fill the gap or is squeezed out of gap. The
                      reduction of seal thickness to outer radius ratio results in
                      an increase in stress concentration at the outer edge of
                      sealant. The developed specimens with a hollow halve steel
                      plate as well as the ones with two hollow halve steel plates
                      appear to be suitable choices for torsional shear strength
                      test, reducing the torque for fracture and stress
                      concentrations. Effects of lack of filling and squeezing out
                      of gap onto the stress distribution are negligible compared
                      to the effect of pre-existing discontinuities.},
