Book Description
Les performances thermomécaniques des composites carbone/carbone permettent leur utilisation thermostructurale. Afin de dimensionner correctement les structures, il est nécessaire de connaître le comportement mécanique du composite sous des sollicitations multiaxiales. Un appareillage spécifique de sollicitations multiaxiales de type traction-cisaillement a été conçu et réalisé lors de ce travail. On a déterminé le comportement mécanique et les différents mécanismes d'endommagement de traction ou de compression dans les axes et hors axes d'orthotropie du matériau. Le modèle utilisé pour rendre compte de cet endommagement est fondé sur la mécanique des milieux continus endommageables, les déformations anélastiques induites par l'endommagement étant traitées par la théorie de la plasticité. Les observations au microscope des modes d'endommagement de la matrice conduisent à la formulation d'hypothèses simplificatrices physiquement acceptables. Le modèle a été identifié à l'aide des essais de traction et de compression dans les axes de symétrie du matériau. Les essais de traction/cisaillement ont permis de compléter l'étude du comportement du matériau et de valider la loi de comportement mécanique sous sollicitations multiaxiales proposée.

Languages : en
Pages : 653
Book Description
The 5th International Congress on Design and Modeling of Mechanical Systems (CMSM) was held in Djerba, Tunisia on March 25-27, 2013 and followed four previous successful editions, which brought together international experts in the fields of design and modeling of mechanical systems, thus contributing to the exchange of information and skills and leading to a considerable progress in research among the participating teams. The fifth edition of the congress (CMSM ́2013), organized by the Unit of Mechanics, Modeling and Manufacturing (U2MP) of the National School of Engineers of Sfax, Tunisia, the Mechanical Engineering Laboratory (MBL) of the National School of Engineers of Monastir, Tunisia and the Mechanics Laboratory of Sousse (LMS) of the National School of Engineers of Sousse, Tunisia, saw a significant increase of the international participation. This edition brought together nearly 300 attendees who exposed their work on the following topics: mechatronics and robotics, dynamics of mechanical systems, fluid structure interaction and vibroacoustics, modeling and analysis of materials and structures, design and manufacturing of mechanical systems. This book is the proceedings of CMSM ́2013 and contains a careful selection of high quality contributions, which were exposed during various sessions of the congress. The original articles presented here provide an overview of recent research advancements accomplished in the field mechanical engineering.

Special Course on Aircraft Dynamics at High Angles of Attack: Experiments and Modelling
Author: North Atlantic Treaty Organization. Advisory Group for Aerospace Research and Development. Fluid Dynamics Panel. Special Course
Publisher:
ISBN:
Category : Aerodynamics
Languages : en
Pages : 154
Book Description
"This report consists of lecture notes of an AGARD Fluid Dynamics Panel Special Course. These notes provide the latest information on the development and use of dynamic experiments in wind tunnels from several of the NATO nations. They address current oscillatory and rotary test techniques, experimental results for typical configurations, and the use of these data for flight mechanics applications. Subject included are: dynamic lift, wing rock, fluid dynamics of rotary flows, mathematical modelling, non-linear data representation, vortex manipulation for control enhancement, and correlations of predictions based on rotary and oscillatory wind-tunnel and flight-test results. The complete course notes are contained in two volumes. The main part of the notes is contained in AGARD Advisory Report 265 (ADA235179). The present volume includes papers on: Unsteady aerodynamics of slender wings; Dynamic stall effects and applications to high performance aircraft; Oscillatory test techniques; Large amplitude oscillations; Oscillatory data for typical configurations; and Forebody vortex control."--Stinet.
