An optimal order finite element method for elliptic interface problems

In this case the plate is known as concentrically stiffened and the problem decomposes into two simpler problems as it happens for unstiffened plates: the in-plane and the bending

In this paper, by use of affine biquadratic elements, we construct and analyze a finite volume element scheme for elliptic equations on quadrilateral meshes.. The scheme is shown to be

In stick regions, located near the outward corners of the section, the shear stresses are low and the velocity vanishes at the boundary (see Fig. Conversely, in slip regions, located

We will focus our study on the approximation of Problem 1.1 with piecewise linear éléments, including numerical intégration, and obtain rates of convergence.. The layout of the paper

Résumé — Cet article est consacre a l'étude d'un problème de Dinchlet avec poids, nous donnons une formulation mixte de ce problème admettant une solution unique, nous obtenons

In addition, we also derive several new results: optimal error estimates are derived for Q ℓ -rectangular FEs (for such elements we don’t know how to obtain error estimates using

In this chapter, we demonstrate a general formulation of the FEM allowing to calculate the diffraction efficiencies from the electromagnetic field diffracted by arbitrarily
