Nitsche's Finite Element Method for Model Coupling in Elasticity
Peter Hansbo, Mats G. Larson
We develop a Nitsche finite element method for a model of Euler--Bernoulli beams with axial stiffness embedded in a two--dimensional elastic bulk domain. The beams have their own d…

Error estimates for the Smagorinsky turbulence model: enhanced stability through scale separation and numerical stabilization
Erik Burman, Peter Hansbo, Mats G. Larson
In the present work we show some results on the effect of the Smagorinsky model on the stability of the associated perturbation equation. We show that in the presence of a spectral…
