A global H (div)-conforming finite element post-processing for stress recovery in nearly incompressible elasticity
In this work, we study the application of a post-processing strategy to recover the stress field
in the linear elasticity problem, with a particular interest in the limit of near incompressibility …

On the energy-sampling stabilization of Nodally Integrated Continuum Elements for dynamic analyses
Nodally integrated elements exhibit spurious modes in dynamic analyses (such as in modal
analysis). Previously published methods involved a heuristic stabilization factor, which may …
