Pages : 402

Book Description
L'oxydation est le mode le plus général de vieillissement des polymères. Peu de domaines d'application de ces matériaux échappent à des préoccupations de durabilité liées au vieillissement oxydant. Les concepteurs et utilisateurs de ces matériaux ont besoin d'outils fiables pour la prédiction de durée de vie. Seule une approche non empirique peut garantir une telle fiabilité. Elle implique une série d'étapes relevant de disciplines différentes comme la chimie organique radicalaire, la physico-chimie macromoléculaire, la physique des processus de transport et la physique des polymères. Le présent ouvrage consacre un chapitre à chacune des étapes de cette démarche en mettant l'accent sur les aspects cinétiques présentés de manière originale. Une attention particulière est portée aux liens entre les différentes disciplines qui, jusqu'ici, avaient tendance à s'ignorer. Les chercheurs et ingénieurs concernés par le problème trouveront dans cet ouvrage des éléments pour accomplir la totalité de la démarche de prédiction de durée de vie, du mécanisme réactionnel à l'évolution des propriétés mécaniques.

Durability of Geotextiles

Durability of Geotextiles PDF Author: Rilem
Publisher: CRC Press
ISBN: 0203626494
Category : Architecture
Languages : en
Pages : 189

Book Description
During the past decade, the use of geotextiles has increased significantly in a wide range of civil engineering applications: road construction, coastal engineering, stabilization of slopes and retaining structures, reinforcement of foundations, drainage etc. This work focuses on the factors which determine the level of long-term performance of these materials such as their mechanical and physical properties and physico-chemical ageing processes. (It includes contributions to an international seminar held at Saint-Remy-les-Chevreuse, France, in November 1986)

Nuclear Materials under Irradiation

Nuclear Materials under Irradiation PDF Author: Serge Bouffard
Publisher: John Wiley & Sons
ISBN: 1394256280
Category : Technology & Engineering
Languages : en
Pages : 241

Book Description
At every stage of the fuel cycle, the materials used are at the heart of nuclear energy safety issues. These materials, which range from steel to polymers, including ceramics, glass, concrete and graphite, are submitted to extreme stresses combining mechanical, thermal and irradiation constraints. The objective of this book is to provide a basis for the research of nuclear materials subjected to irradiation, with the desire to contextualize them in the industrial environment. Therefore, most of the chapters are co-authored and contain a mix of basic and applied research. The reader will find chapters on nuclear reactor materials (structural materials, neutron absorbers, moderators and nuclear fuel) and on materials in waste management (glass, concrete and organic materials). These material chapters are complemented by more general information on defects and their creation, radiolysis and irradiation and characterization tools.

Organic Materials for Sustainable Civil Engineering

Organic Materials for Sustainable Civil Engineering PDF Author: Yves Mouton
Publisher: John Wiley & Sons
ISBN: 1118616693
Category : Business & Economics
Languages : en
Pages : 511

Book Description
This book provides an inventory of organic materials and products, the major components of all civil engineering projects, in terms of their scientific and technical background, including the regulations that cover their use and their predicted useful life. Such materials include: bitumen on the roads; geotextiles for retaining walls; membranes for bridges; tunnel and reservoir waterproofing; paint binders to protect metallic and concrete structures or to realize road markings; injection resins; gluing products; concrete admixtures; and composite materials. The presentation is based on a physicochemical approach, which is essential if these products are to be considered as part of sustainable development: as such, those studying or working in these fields will find this an invaluable source of information.

Polymer Fracture

Polymer Fracture PDF Author: H. - H. Kausch
Publisher: Springer Science & Business Media
ISBN: 3642964605
Category : Technology & Engineering
Languages : en
Pages : 341

Book Description
This book on "Polymer Fracture" might as well have been called "Kinetic Theory of Polymer Fracture". The term "kinetic theory", however, needs some de finition or, at least, some explanation. A kinetic theory deals with and particu larly considers the effect of the existence and discrete size, of the motion and of the physical properties of molecules on the macroscopic behavior of an ensemble, gaseous or other. A kinetic theory of strength does have to consider additional aspects such as elastic and anelastic deformations, chemical and physical reactions, and the sequence and distribution of different disintegration steps. In the last fifteen years considerable progress has been made in the latter do mains. The deformation and rupture of molecular chains, crystals, and morphologi cal structures have been intensively investigated. The understanding of the effect of those processes on the strength of polymeric materials has especially been furthered by the development and application of spectroscopical methods (ESR, IR) and of the tools offracture mechanics. It is the aim of this book to relate the conventional and successful statistical, parametrical, and continuum mechanical treatment of fracture phenomena to new results on the behavior of highly stressed molecular chains.
