Since the beginning of the century the technological desire to master the fracture of metals,
concrete or polymers has boosted research and has left behind an overwhelming amount of …

A phenomenological theory of the fluctuations of velocity occurring in a fully developed
homogeneous and isotropic turbulent flow is presented. The focus is made on the fluctuations of …

À partir de mesures de champs de déplacement exclusivement, il est proposé d'identifier des
champs d'endommagement à la surface du matériau. Une formulation aux éléments finis …

Un algorithme de corrélation d'images numériques est présenté pour mesurer des champs
de déplacement tridimensionnel avec des images à trois dimensions. La base cinématique …

The current state of the art of digital image correlation, where displacements can be
determined for values less than one pixel, enables one to better characterise the behaviour of …

Relying on contact dynamics simulations, we study the statistical distribution of contact forces
inside a confined packing of circular rigid disks with solid friction. We find the following:(1) …

Digital image correlation is an appealing technique for studying crack propagation in brittle
materials such as ceramics. A case study is discussed where the crack geometry, and the …

Reliability and accuracy of the determination of self-affine exponents are studied and quantified
from the analysis of synthetic self-affine profiles and surfaces. The self-affine exponent is …

L'enquête nationale Transports et déplacements (ENTD) donne un panorama général et
cohérent de l'ensemble des aspects de la mobilité des Français. En effet, elle permet de décrire …

We show how wavelet techniques allow to derive irregularity properties of functions on two
particular examples: Lacunary Fourier series and some Gaussian random processes. Then, …
