Book Description
CETTE ETUDE, REALISEE DANS LE CADRE DU GROUPEMENT SCIENTIFIQUE FRANCAIS COMPORTEMENT THERMOMECANIQUE DES COMPOSITES CERAMIQUE/CERAMIQUE A FIBRES, A POUR OBJECTIFS LA CARACTERISATION EXPERIMENTALE ET LA MODELISATION DU COMPORTEMENT MECANIQUE, A TEMPERATURE AMBIANTE, EN TRACTION UNIAXIALE, DE COMPOSITES SIC/SIC ELABORES PAR LA SEP. NOUS AVONS ADOPTE UNE APPROCHE MULTI-ECHELLE: DIFFERENTS MATERIAUX ONT SUCCESSIVEMENT ETE CONSIDERES. LES TORONS: COMPOSITES UNIDIRECTIONNELS CONSTITUES D'ENVIRON 500 FIBRES DE SIC NICALON IMPREGNEES, PAR INFILTRATION CHIMIQUE EN PHASE VAPEUR (CVI), PAR LA MATRICE SIC. LES COMPOSITES MONOCOUCHES: NAPPES DE TORONS DE FIBRES DE SIC TISSES, IMPREGNEES PAR LA MATRICE SIC SELON LE MEME PROCEDE DE CVI. LES MATERIAUX MULTICOUCHES: SUPERPOSITIONS DE STRATES DE TORONS DE FIBRES TISSES, INFILTREES PAR LA MATRICE SIC. LA MODELISATION NUMERIQUE PAR ELEMENTS FINIS PROPOSEE EST FONDEE SUR UNE DESCRIPTION STATISTIQUE DU COMPORTEMENT DES TORONS. CES DERNIERS SONT EN EFFET CARACTERISES PAR UNE DISPERSION IMPORTANTE DE LEURS CARACTERISTIQUES MECANIQUES (SEUILS D'ENDOMMAGEMENT ET DE RUPTURE). CE PHENOMENE NON NEGLIGEABLE A DONC ETE INTRODUIT DANS LA MODELISATION. PAR AILLEURS, L'OBSERVATION EN MICROSCOPIE (OPTIQUE, ELECTRONIQUE A BALAYAGE) DES DIFFERENTS MATERIAUX, A PERMIS DE METTRE EN EVIDENCE LES PHENOMENES PHYSIQUES SUPPLEMENTAIRES SE PRODUISANT A CHAQUE ECHELLE (FISSURATION MATRICIELLE, DELAMINAGES). LA PRISE EN COMPTE DE CES PARAMETRES DANS LES SIMULATIONS A FOURNI UNE DESCRIPTION CORRECTE DU COMPORTEMENT MECANIQUE ET DE LA DISPERSION DES CARACTERISTIQUES MECANIQUES DES DIFFERENTS MATERIAUX: DES COMPARAISONS CALCUL/EXPERIENCE SONT REALISEES A CHAQUE ECHELLE

Book Description
In mechanical engineering and structural analysis there is a significant gap between the material models currently used by engineers for industry applications and those already available in research laboratories. This is especially apparent with the huge progress of computational possibilities and the corresponding dissemination of numerical tools in engineering practice, which essentially deliver linear solutions. Future improvements of design and life assessment methods necessarily involve non-linear solutions for inelastic responses, in plasticity or viscoplasticity, as well as damage and fracture analyses. The dissemination of knowledge can be improved by software developments, data base completion and generalization, but also by information and training. With such a perspective Non-Linear Mechanics of Materials proposes a knowledge actualization, in order to better understand and use recent material constitutive and damage modeling methods in the context of structural analysis or multiscale material microstructure computations.

Book Description
This book deals with a group of architectured materials. These are hybrid materials in which the constituents (even strongly dissimilar ones) are combined in a given topology and geometry to provide otherwise conflicting properties. The hybridization presented in the book occurs at various levels - from the molecular to the macroscopic (say, sub-centimeter) ones. This monograph represents a collection of programmatic chapters, defining archimats and summarizing the results obtained by using the geometry-inspired materials design. The area of architectured or geometry-inspired materials has reached a certain level of maturity and visibility for a comprehensive presentation in book form. It is written by a group of authors who are active researchers working on various aspects of architectured materials. Through its 14 chapters, the book provides definitions and descriptions of the archetypes of architectured materials and addresses the various techniques in which they can be designed, optimized, and manufactured. It covers a broad realm of archimats, from the ones occurring in nature to those that have been engineered, and discusses a range of their possible applications. The book provides inspiring and scientifically profound, yet entertaining, reading for the materials science community and beyond.

Book Description
Presenting a unified approach, this book focusses on the concepts and theoretical methods that are necessary for an understanding of the physics and chemistry of the fluid state. The authors do not attempt to cover the whole field in an encyclopedic manner. Instead, important ideas are presented in a concise and rigorous style, and illustrated with examples from both simple molecular liquids and more complex soft condensed matter systems such as polymers, colloids, and liquid crystals.

Book Description
On the roots of continuum mechanics in differential geometry -- a review.- Cosserat media.- Cosserat-type shells.- Cosserat-type rods.- Micromorphic media.- Electromagnetism and generalized continua.- Computational methods for generalized continua. The need of generalized continua models is coming from practice. Complex material behavior sometimes cannot be presented by the classical Cauchy continua. At present the attention of the scientists in this field is focused on the most recent research items • new models, • application of well-known models to new problems, • micro-macro aspects, • computational effort, and • possibilities to identify the constitutive equations The new research directions are discussed in this volume - from the point of view of modeling and simulation, identification, and numerical methods.
