Sixth-order boundary value problems of a one-parameter gradient-elastic Kirchhoff plate model are formulated in a weak form within an H 3 Sobolev space setting with the …
The fourth-order boundary value problems of one parameter gradient-elastic bar and plane strain/stress models are formulated in a variational form within an H 2 Sobolev space setting …
An a posteriori error estimator for a quadratic C0-interior penalty method for the biharmonic problem Page 1 IMA Journal of Numerical Analysis (2010) 30, 777–798 doi:10.1093/imanum/drn057 …
We introduce a residual-based a posteriori error indicator for discontinuous Galerkin discretizations of the biharmonic equation with essential boundary conditions. We show that …

A new approach is introduced for deriving a mixed variational formulation for Kirchhoff plate bending problems with mixed boundary conditions involving clamped, simply supported …
We develop a method to compute the-conforming finite element approximation to planar fourth order elliptic problems without having to implement elements. The algorithm consists …

We introduce a new mixed method for the biharmonic problem. The method is based on a formulation where the biharmonic problem is rewritten as a system of four first-order …
