Discontinuous Galerkin methods for incompressible and nearly incompressible elasticity by Nitsche's method
Artikel i vetenskaplig tidskrift, 2002
We propose and analyze a discontinuous finite element method for nearly incompressible linear elasticity on triangular meshes. We
show optimal error estimates that are uniform with respect to Poissons ratio. The method is thus locking free. We also introduce an
equivalent mixed formulation, allowing for completely incompressible elasticity problems. Numerical results are presented.
