Book excerpt: LE TRAVAIL QUE NOUS PRESENTONS PORTE SUR LA REPONSE A DES SOLLICITATIONS ELECTRIQUES DE MATERIAUX COMPOSITES EPOXY-FIBRES DE VERRE. LA PREMIERE PARTIE DU TRAVAIL PORTE SUR LA REPONSE A UN ECHELON DE TENSION. ON MONTRE QUE POUR DES TEMPERATURES INFERIEURES A UNE ZONE 80-100#OC, LA REPONSE EST DE TYPE DIPOLAIRE ET LE MATERIAU A UN COMPORTEMENT LINEAIRE AUSSI BIEN EN REGIME TRANSITOIRE QU'EN REGIME PERMANENT. AU-DELA DE CETTE ZONE DE TEMPERATURE UNE CONTRIBUTION IONIQUE A LA CONDUCTION EST MISE EN EVIDENCE. CELA CONDUIT A L'ETABLISSEMENT D'UNE CHARGE D'ESPACE LOCALISEE AUX INTERFACES MATRICE-FIBRE DE VERRE. LA ZONE DE TEMPERATURE SEPARANT LES DEUX TYPES DE COMPORTEMENTS EST LA ZONE DE LA TEMPERATURE DE TRANSITION VITREUSE QUE NOUS AVONS MISE EN EVIDENCE PAR ANALYSE THERMIQUE DIFFERENTIELLE. UNE SECONDE PARTIE EST L'ETUDE DE LA REPONSE EN ALTERNATIF (PERMITTIVITE COMPLEXE). ON MET EN EVIDENCE UN PIC DE RELAXATION DIPOLAIRE QUI EST LIE A LA REPONSE DE LA MATRICE EPOXY. OUTRE CE COMPORTEMENT ASSEZ CONVENTIONNEL ON A OBSERVE UN COMPORTEMENT ANORMAL DU COMPOSITE LORSQUE CELUI-CI A UNE TENEUR EN EAU SUPERIEURE A 0,8%. CE COMPORTEMENT EST ASSOCIE A L'EXISTENCE DE MICROFISSURES OU DE DELAMINATION A L'INTERFACE EPOXY-VERRE. DANS UN DERNIER PARAGRAPHE, ON DETAILLE LES EFFETS DE L'ABSORPTION D'HUMIDITE SUR LA REPONSE DIELECTRIQUE. LA DERNIERE PARTIE DE CE TRAVAIL EST RELATIVE A L'ACTION COUPLEE DE CONTRAINTES MECANIQUES ET ELECTRIQUES. ALORS QU'EN DESSOUS DE LA TRANSITION VITREUSE LA CONTRAINTE MECANIQUE EN FLEXION NE JOUE PAS SUR LA REPONSE ELECTRIQUE, POUR T=100#OC, ON OBSERVE UN NIVEAU DE CONDUCTION BEAUCOUP PLUS IMPORTANT ET LA CONSTITUTION DE CHARGES D'ESPACES MODIFIANT TRES SENSIBLEMENT L'ALLURE DES COURANTS DE CHARGES ET DE DECHARGE. CET EFFET PEUT ALLER JUSQU'A UNE INVERSION DE POLARITE DU COURANT DE DECHARGE. UNE AMORCE DE MODELISATION DE CE PHENOMENE A ETE PROPOSEE
Book Synopsis Adhesion between polymers and concrete / Adhésion entre polymères et béton by : H. R. Sasse
Download or read book Adhesion between polymers and concrete / Adhésion entre polymères et béton written by H. R. Sasse and published by Springer. This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book Synopsis Flow Sensing in Air and Water by : Horst Bleckmann
Download or read book Flow Sensing in Air and Water written by Horst Bleckmann and published by Springer Science & Business Media. This book was released on 2014-01-22 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, leading scientists in the fields of sensory biology, neuroscience, physics and engineering explore the basic operational principles and behavioral uses of flow sensing in animals and how they might be applied to engineering applications such as autonomous control of underwater or aerial vehicles. Although humans possess no flow-sensing abilities, countless aquatic (e.g. fish, cephalopods and seals), terrestrial (e.g. crickets and spiders) and aerial (e.g. bats) animals have flow sensing abilities that underlie remarkable behavioral feats. These include the ability to follow silent hydrodynamic trails long after the trailblazer has left the scene, to form hydrodynamic images of their environment in total darkness, and to swim or fly efficiently and effortlessly in the face of destabilizing currents and winds.
Book Synopsis Flexoelectricity in Liquid Crystals by : Agnes Buka
Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

Download or read book Nonlinear Optical Materials written by Jerome V. Moloney and published by Springer Science & Business Media. This book was released on 1998-08-13 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical methods play a significant role in the rapidly growing field of nonlinear optical materials. This volume discusses a number of successful or promising contributions. The overall theme of this volume is twofold: (1) the challenges faced in computing and optimizing nonlinear optical material properties; and (2) the exploitation of these properties in important areas of application. These include the design of optical amplifiers and lasers, as well as novel optical switches. Research topics in this volume include how to exploit the magnetooptic effect, how to work with the nonlinear optical response of materials, how to predict laser-induced breakdown in efficient optical devices, and how to handle electron cloud distortion in femtosecond processes.
