A reduced basis method for frictional contact problems formulated with Nitsche's method

Idrissa Niakh, Guillaume Drouet, Virginie Ehrlacher +1

We develop an efficient reduced basis method for the frictional contact problem formulated using Nitsche's method. We focus on the regime of small deformations and on Tresca fricti…

-hybrid high-order methods for biharmonic problems

Zhaonan Dong, Alexandre Ern

We devise and analyze -conforming hybrid high-order (HHO) methods to approximate biharmonic problems with either clamped or simply supported boundary conditions. -conform…

Local decay rates of best-approximation errors using vector-valued finite elements for fields with low regularity and integrable curl or divergence

Zhaonan Dong, Alexandre Ern, Jean-Luc Guermond

We estimate best-approximation errors using vector-valued finite elements for fields with low regularity in the scale of fractional-order Sobolev spaces. By assuming additionally t…

Hybrid high-order method for singularly perturbed fourth-order problems on curved domains

Zhaonan Dong, Alexandre Ern

We propose a novel hybrid high-order method (HHO) to approximate singularly perturbed fourth-order PDEs on domains with a possibly curved boundary. The two key ideas in devising th…

Hybrid high-order methods. A primer with application to solid mechanics

Matteo Cicuttin, Alexandre Ern, Nicolas Pignet

This book is organized into eight chapters. The first three gently introduce the basic principles of hybrid high-order methods on a linear diffusion problem, the key ideas underlyi…

On the derivation of guaranteed and p-robust a posteriori error estimates for the Helmholtz equation

T. Chaumont-Frelet, A. Ern, M. Vohralík

We propose a novel a posteriori error estimator for conforming finite element discretizations of two- and three-dimensional Helmholtz problems. The estimator is based on an equilib…
