A new locking-free polygonal plate element for thin and thick plates based on Reissner-Mindlin plate theory and assumed shear strain fields

, 2018
A new $n-$ noded polygonal plate element is proposed for the analysis of plate structures comprising of thin and thick members. The formulation is based on the discrete Kirchhoff Mindlin theory.

Osteoarthritis: Epidemiology, Pathogenesis, and Treatment

MedComm, Volume 7, Issue 4, April 2026.
Osteoarthritis is a prevalent degenerative joint disease with a growing global burden. Its development involves complex interactions among epidemiological factors, pathological changes, molecular signaling, and epigenetic regulation. Understanding these mechanisms provides insights into disease progression and supports the development of therapeutic ...

An agglomeration-based massively parallel non-overlapping additive Schwarz preconditioner for high-order discontinuous Galerkin methods on polytopic grids

, 2019
In this article we design and analyze a class of two-level non-overlapping additive Schwarz preconditioners for the solution of the linear system of equations stemming from discontinuous Galerkin discretizations of second-order elliptic partial ...

On low order mimetic finite difference methods

, 2012
These pages review two families of mimetic finite difference methods: the mixed-type methods presented in [Brezzi, Lipnikov, and Simoncini, M3AS, 2005] and the nodal methods of [Brezzi, Buffa, and Lipnikov, M2AN, 2009]. The purpose of this exercise it to highlight the similitudes underlying the construction of the two families.

Gradient schemes: a generic framework for the discretisation of linear, nonlinear and nonlocal elliptic and parabolic equations

, 2013
International audienceGradient schemes are nonconforming methods written in discrete variational formulation and based on independent approximations of functions and gradients, using the same degrees of freedom.
