A decomposition result for Kirchhoff plate bending problems and a new discretization approach
Katharina Rafetseder, Walter Zulehner
A new approach is introduced for deriving a mixed variational formulation for Kirchhoff plate bending problems with mixed boundary conditions involving clamped, simply supported, a…
