  author={Astrid Pechstein and Joachim Sch{\"o}berl},
SUMMARY In this paper, we present a family of mixed finite elements, which are suitable for the discretization of slim domains. The displacement space is chosen as Nedelec's space of tangential continuous elements, whereas the stress is approximated by normal–normal continuous symmetric tensor-valued finite elements. We show stability of the system on a slim domain discretized by a tensor product mesh, where the constant of stability does not depend on the aspect ratio of the discretization… CONTINUE READING
