Book Description
CE TRAVAIL CONCERNE L'ELABORATION D'UN MODELE ELASTO-PLASTIQUE NON LINEAIRE D'ANALYSE DES STRUCTURES EN ACIER CONSIDERANT L'EVOLUTION DE LA PLASTICITE SUIVANT LES SECTIONS TRANSVERSALES ET LE LONG DES ELEMENTS, L'INFLUENCE DES CONTRAINTES RESIDUELLES ET L'ECROUISSAGE. LE MODELE EST FONDE SUR UNE FORMULATION ANALYTIQUE DES EFFORTS ET DES RIGIDITES DES SECTIONS EN FONCTION DES DEFORMATIONS GLOBALES. IL EST DEVELOPPE POUR DES RELATIONS CONSTITUTIVES ELASTIQUE NON LINEAIRE ET ELASTOPLASTIQUE. SES POTENTIALITES SONT MONTREES PAR UNE ETUDE THEORIQUE DU FLAMBEMENT PAR BIFURCATION EN REGIME ELASTOPLASTIQUE. L'APPLICATION DES MODELES DE SECTION EST MENEE PAR L'ETUDE DES EFFETS DE LA FORME DE LA SECTION TRANSVERSALE, DE LA MODELISATION DE LA LOI CONSTITUTIVE, DE L'INTERACTION DES DEFORMATIONS GLOBALES ET DES PHENOMENES D'INSTABILITE LOCALE. LES RELATIONS INCREMENTALES SONT ETABLIES AVEC UNE DESCRIPTION LAGRANGIENNE ACTUALISEE. LA PRISE EN COMPTE DE LA GEOMETRIE DEFORMEE DES BARRES EST FONDEE SUR LA THEORIE DE MARGUERRE. LA SEMI-RIGIDITE DES ASSEMBLAGES EST PRISE EN COMPTE. LA DETERMINATION DE LA REPONSE NON LINEAIRE DE LA STRUCTURE EST GOUVERNEE PAR UN PILOTAGE EN SPHERE APPLIQUE A LA METHODE DE NEWTON-RAPHSON. PLUSIEURS EXEMPLES D'APPLICATION MONTRENT LES CARACTERISTIQUES SPECIFIQUES DU MODELE ET VALIDENT LES RESULTATS. C'EST LE CAS NOTAMMENT DE L'EVALUATION DE L'INFLUENCE DES REGLES DE CALCUL DE LA LONGUEUR DE FLAMBEMENT PROPOSEE PAR L'EUROCODE 3 SUR LA DETERMINATION DE LEUR CAPACITE PORTANTE MAXIMALE

Book Description
This book gives a comprehensive view of the most recent major international research in the field of tolerancing, and is an excellent resource for anyone interested in Computer Aided Tolerating. It is organized into 4 parts. Part 1 focuses on the more general problems of tolerance analysis and synthesis, for tolerancing in mechanical design and manufacturing processes. Part 2 specifically highlights the simulation of assembly with defects, and the influence of tolerances on the quality of the assembly. Part 3 deals with measurement aspects, and quality control throughout the life cycle. Different measurement technologies and methods for estimating uncertainty are considered. In Part 4, different aspects of tolerancing and their interactions are explored, from the definition of functional requirement to measurement processes in a PLM approach.

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
This publication results from a technical meeting on phenomenology and technologies relevant to in-vessel melt retention (IVMR) and ex-vessel corium cooling (EVCC). The purpose of the publication is to capture the state of knowledge, at the time of that meeting, related to phenomenology and technologies as well as the challenges and pending issues relevant to IVMR and EVCC for water cooled reactors by summarizing the information provided by the meeting participants in a form useful to practitioners in Member States.
