Anisotropic behaviour law for sheets used in stamping: A comparative study of steel and aluminium [PDF]

open access: yes, 2003
For a car manufacturer, reducing the weight of vehicles is an obvious aim. Replacing steel by aluminium moves towards that goal. Unfortunately, aluminium's stamping numerical simulation results are not yet as reliable as those of steel.

Boundary singularities of positive solutions of some nonlinear elliptic equations [PDF]

open access: yes, 2007
We study the behaviour near a boundary point a of any positive solution of a nonlinear elliptic equations with forcing term which vanishes on the boundary except at a.

Asymptotic behavior of an elastic beam fixed on a small part of one of its extremities [PDF]

open access: yes, 2004
We study the asymptotic behavior of the solution of an anisotropic, heterogeneous, linearized elasticity problem in a cylinder whose diameter $\epsilon$ tends to zero.

Some remarks on the damage unilateral effect modelling for microcracked materials [PDF]

open access: yes, 2002
This study deals with the macroscopic modelling of the mechanical behaviour of microcracked materials and particularly with the unilateral aspect of such damage which leads, at the closure of microcracks, to a partial damage deactivation.

Experimental creep behaviour determination of cladding tube materials under multi-axial loadings [PDF]

open access: yes, 2009
Cladding tubes are structural parts of nuclear plants, submitted to complex thermomechanical loadings. Thus, it is necessary to know and predict their behaviour to preserve their integrity and to enhance their lifetime.

Compact A15 Frank-Kasper nano-phases at the origin of dislocation loops in face-centred cubic metals

open access: yesNature Communications, 2023
It is generally considered that the elementary building blocks of defects in face-centred cubic (fcc) metals, e.g., interstitial dumbbells, coalesce directly into ever larger 2D dislocation loops, implying a continuous coarsening process. Here, we reveal

Interference with the retinoic acid signalling pathway inhibits the initiation of teeth and caudal primary scales in the small-spotted catshark Scyliorhinus canicula [PDF]

open access: yesPeerJ, 2023
The retinoic acid (RA) pathway was shown to be important for tooth development in mammals, and suspected to play a key role in tooth evolution in teleosts.

DE L’ETAT-REPUBLICAIN, DE LA NECESSITE DE LA PREVISIBILITE DES COMPORTEMENTS DES CITOYENS ET DE LA PORTEE DU CARACTERE STRATEGIQUE DES LOIS ET DES VALEURS : Un regard Antropologico - sociologique sur le cas de la Rd. Congo

open access: yesRegard lucide, 2023
L’analyse planche sur la nécessité de la prévisibilité des comportements des citoyens dans un Etat-républicain. Elle soutient que ceci ne peut être possible que par la référence aux valeurs républicaines et éthiques, ainsi que par l’observance des ...

La mort naturelle d'une femelle chimpanzé âgée au sein de son groupe

open access: yesRevue de Primatologie, 2015
A l'exception des jeunes bébés malades ou tués par d'autres individus, le moment de la mort chez les grands singes anthropoïdes reste un événement rarement observé dans la nature.
