Dans ce travail, nous présentons et analysons un élément fini non conforme en quadrangles. Nous obtenons une estimation d'erreur a priori optimale pour des quadrangles réguliers arbitraires. Nous présentons également l'idée d'extension tridimensionnelle de cet élément.
We introduce and analyze a simple nonconforming quadrilateral finite element and then we derive optimal a priori error estimates for arbitrary regular quadrilaterals. The idea of extension to some non-conforming elements for three-dimensional hexahedrons is also presented.
