Do locking-free finite element schemes lock for holey Reissner-Mindlin plates with mixed boundary conditions?
Mark Ainsworth, Charles Parker
We revisit finite element discretizations of the Reissner-Mindlin plate in the case of non-simply connected (holey) domains with mixed boundary conditions. Guided by the de Rham co…

A Mass Conserving Mixed hp-FEM Scheme for Stokes Flow. Part III: Implementation and Preconditioning
Mark Ainsworth, Charles Parker
This is the third part in a series on a mass conserving, high order, mixed finite element method for Stokes flow. In this part, we study a block-diagonal preconditioner for the ind…
