G Taraschi, MR Correa, AS Pinto, CO Faria - Applied Mathematics and …, 2024 - Elsevier
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

R Sivapuram, P Krysl - Finite Elements in Analysis and Design, 2019 - Elsevier
Nodally integrated elements exhibit spurious modes in dynamic analyses (such as in modal
analysis). Previously published methods involved a heuristic stabilization factor, which may …
