Condition d’intégrabilité d’une loi d’hypoélaticité

We propose a geometric reformulation of hypoelasticity in terms of 1-forms (powers) on the manifold of the Riemannian metrics. From this reformulation, we establish a new necessary condition for the integrability of an hypoelasticity law, similar to…

Vers une nouvelle stratégie PGD pour la simulation numérique de structures élancées

Effective models for slender structures derived from well-known theories are justified within the limit of a small thickness, and may therefore prove limited for intermediate slenderness. On the other hand, direct 3D simulation of such structures is…

Modélisation simplifiée de l'usure dans les liaisons à contact conforme – Application aux aubes à calages variables

Mastering engine maintenance is a key issue for airline companies. To avoid aircraft being grounded for extended and costly periods, it is strategically important to anticipate maintenance cycles, and therefore the wear of systems. In this context,…

Performing Stereo-Measurements with Optimal Patterns Processed by Localised Spectrum Analysis

Background: Localised Spectrum Analysis is a full-field measurement method which enables processing optimal patterns (i.e. checkerboard patterns) and obtaining high metrological performance. However, LSA was still limited to 2D cases. Objective:…

Control of the accuracy and improvement of the convergence rate of a LATIN-based multiscale strategy for frictional contact problems

This paper deals with the control and improvement of the convergence of the interface contact quantities in the framework of a multiscale strategy for the resolution of time-dependent frictional contact problems. The considered strategy is the…
