Tribological behavior of composites fabricated by reactive SPS sintering in Ti‐Si‐C system

Youcef Hadji, Abdessabour Benamor, Nabil Chiker, Adel Haddad, Nacer Tala-Ighil, Jean-Pierre Erauw, Vedi Dupont, Arnaud Tricoteaux, Christelle Nivot, Anthony Thuault, Mohamed Hadji

In this study, wear and friction behavior of two based-composites from the Ti-Si-C system, (40 wt% TiC; 28 wt% Ti5Si3; 17 wt% Ti3SiC2) and (18 wt% TiC; 26 wt% Ti5Si3; 41 wt% Ti3SiC2) reinforced by 15 wt% of large size SiC (100-150 µm) particles were investigated. The four-phase composites exhibited…

Existence and multiplicity of solutions for elliptic problems with critical growth in the gradient, Existence et multiplicité de solutions pour des problèmes elliptiques avec croissance critique dans le gradient

Antonio J. Fernández Sánchez

In this thesis, we provide existence, non-existence, uniqueness and multiplicity results for partial differential equations with critical growth in the gradient. The principal techniques employed in our proofs are variational techniques, lower and upper solution theory, a priori estimates and…, Dans cette thèse, nous donnons des résultats d’existence, de non-existence, d’unicité et de multiplicité de solutions pour des équations aux dérivées partielles avec croissance critique dans le gradient. Les principales méthodes utilisées dans nos preuves sont des arguments variationnels, la…

Monomial Representations of Discrete Type of an Exponential Solvable Lie Group

Ali Baklouti, Hidenori Fujiwara, Jean Ludwig

Let G be an exponential solvable Lie group, H an analytic subgroup of G and χ a unitary character of H. We study some problems related to the induced representation τ=indGHχ of G when τ has multiplicities either finite or infinite of discrete type. In particular, we are interested in the Plancherel…

Comparing variational methods for the hinged Kirchhoff plate with corners

Colette De Coster, Serge Nicaise, Guido Sweers

The hinged Kirchhoff plate model contains a fourth order elliptic differential equation complemented with a zeroeth and a second order boundary condition. On domains with boundaries having corners the strong setting is not well‐defined. We here allow boundaries consisting of piecewise C2, 1‐curves…

A posteriori error estimates for a fully discrete approximation of Sobolev equations

Serge Nicaise, Fatiha Bekkouche

The paper presents an a posteriori error estimator for a (piecewise linear) conforming finite element approximation of some (linear) Sobolev equations in R d , d = 2 or 3, using implicit Euler's scheme. For this discretization, we derive a residual indicator, which uses a spatial residual…, L'accès aux articles de la revue « Confluentes Mathematici » (http://cml.cedram.org/), implique l'accord avec les conditions générales d'utilisation (http://cml.cedram.org/legal/).
