Discrete compactness for a discontinuous Galerkin approximation of Maxwell's system

Emmanuel Creusé, Serge Nicaise

In this paper we prove the discrete compactness property for a discontinuous Galerkin approximation of Maxwell's system on quite general tetrahedral meshes. As a consequence, a discrete Friedrichs inequality is obtained and the convergence of the discrete eigenvalues to the continuous ones is…

Anisotropic a posteriori error estimation for the mixed discontinuous Galerkin approximation of the Stokes problem

Emmanuel Creusé, Serge Nicaise

The paper presents a posteriori error estimates for the mixed discontinuous Galerkin approximation of the stationary Stokes problem. We consider anisotropic finite element discretizations, i.e. elements with very large aspect ratio. Our analysis covers two- and three-dimensional domains. Lower and…

New considerations about the fracture mode of PZT ceramics

Olivier Guillon, Dominique Perreux, Frédéric Thiebaud, Christian Courtois, Philippe Champagne, Anne Leriche, Jacques Crampon

Sintered bulk ceramics, such as PZT are brittle materials. This macroscopically implies a statistical distribution of the ultimate strengths, because defects, such as pores or cracks are responsible for the initiation of the specimen failure. Another aspect of this fracture phenomenon is the crack…

Ce rapport décrit les fouilles de Termez, dans la citadelle (céramique hellénistique, sépultures de l'époque islamique) ; à Tchingiz Tepe (fortifications, temple, four, protomé de lion) et à Payon Kourgane. Il traite aussi du bouddhisme en Bactriane., This report describes the excavations at Termez, in the citadel (Hellenistic ware, burial in the Islamic World) ; at Tchingiz Tepe (fortification, temple, kiln, lion's protome). It deals with the Bactrian buddhism.

On-line characterization of silica gels by acoustic near field

B. Cros, M. Pauthe, Mohamed Rguiti, J.-Y. Ferrandis

The acoustic near field technique consists in studying the features of the resonance state of an acoustic horn. The alterations of the resonance curve are investigated as a function of the evolution of the rheological properties of the medium to characterize. The contact between the sample and the…

Influence of porosity on Young's modulus and Poisson's ratio in alumina ceramics

M. Asmani, Christine Kermel, Anne Leriche, Mohamed Ourak

This work presents a study on the influence of the porosity level on Young's modulus and Poisson's ratio of sintered alumina. A non-destructive technique using ultrasonic waves was used to determine the different parameters. Longitudinal and transverse wave velocities are measured by…
