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 Composite Sheet Forming written by D. Bhattacharyya and published by Elsevier. This book was released on 1997-06-18 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sheet forming is the most common process used in metal forming and is therefore constantly being adapted or modified to suit the needs of forming composite sheets. Due to the increasing availability of various types of fibre reinforced polymeric sheets, especially with thermoplastic matrices, the scope of use of such materials is rapidly expanding in the automobile, building, sports and other manufacturing industries beyond the traditional areas of aerospace and aircraft applications. This book contains twelve chapters and attempts to cover different aspects of sheet forming including both thermoplastic and thermosetting materials. In view of the expanded role of fibre reinforced composite sheets in the industry, the book also describes some non-traditional applications, processes and analytical techniques involving such materials.The first chapter is a brief introduction to the principles of sheet metal forming. The next two chapters introduce the various forms of materials, manufacturing techniques and the fundamentals of computer simulation. Chapter 4 describes the different aspects of thermoforming of continuous fibre reinforced thermoplastics and the following chapter studies the shear and frictional behaviour of composite sheets during forming. Chapter 6 explores the possibility of applying the grid strain analysis method in continuous fibre reinforced polymeric sheets. The next two chapters address fundamental concepts and recent developments in finite element modelling and rheology. Chapter 9 introduces the theory of bending of thermoplastic composite sheets and shows a novel way of determining both longitudinal and transverse viscosities through vee-bend tests. A significant expansion in the usage of composite materials is taking place in biomedical areas. Chapter 10 discusses the thermoforming of knitted fabric reinforced thermoplastics for load bearing and anisotropic bio-implants. The final chapter introduces roll forming, a commonly used rapid manufacturing process for sheet metals, and discusses the possibility of applying it economically for continuous reinforced thermoplastic sheets.

Available in PDF, EPUB and Kindle. Book excerpt: Non-crimp fabric (NCF) composites are reinforced with mats of straight (non-crimped) fibres, giving them such advantages as strength, ease of handling and low manufacturing costs. Non-crimp fabric composites provides a comprehensive review of the use of NCF composites, their manufacture and applications in engineering.Part one covers the manufacture of non-crimp fabrics, including also topics such as structural stitching and automated defect analysis. Part two goes on to discuss the manufacture of non-crimp fabric composites, with chapters covering such topics as deformability and permeability of NCF. Part three focuses on the properties of NCF composites, with chapters on stiffness and strength, damage progression and fatigue. Finally, part four covers the applications of NCF composites, including chapters on the aerospace and automotive industries as well as wind turbines and helicopter applications. The book concludes with a discussion of cost analysis of NCF composites in engineering applications.With its distinguished editor and international team of expert contributors, Non-crimp fabric composites is an essential reference for composite manufacturers and structural and mechanical engineers in industries using NCF composites, as well as academics with a research interest in the field. - Provides a comprehensive review of the use of NCF composites, their manufacture and applications in engineering - Reviews the manufacture of non-crimp fabrics, including also topics such as structural stitching and automated defect analysis - Examines the properties of NCF composites considering stiffness and strength, damage progression and fatigue

Download or read book Simulation de la mise en forme de renforts NCF de composites basée sur des approches mesoscopiques written by Ruochen Zheng and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pour parvenir à une fabrication efficace et exempte de défauts de renforts fibreux tout en minimisant la nécessité de tests expérimentaux longs et coûteux, il est nécessaire de développer des techniques de simulation et d'optimisation fiables du procédé de mise en forme. Les renforts composites NCF (Non-Crimp Fabric) promettent des performances structurales exceptionnelles, mais la mise en forme de ces matériaux est délicate. Sa complexité découle des mécanismes de déformation spécifiques de ce type de renforts, principalement influencés par les motifs de couture complexes qui lient subtilement les fibres entre elles. Dans cette étude, nous proposons une approche de modélisation par éléments finis à l'échelle mésoscopique pour relever ce défi. Ici, nous traitons les mèches comme un milieu continu, tandis que les coutures environnantes sont soigneusement représentées à l'aide d'éléments poutres. Pour capturer les caractéristiques de déformation des mèches, nous utilisons une loi hyperélastique, complétée par des éléments poutres intégrés pour découpler leur comportement en flexion. De plus, nous introduisons une étape de précontrainte pour simuler la tension due au tricotage des coutures et modéliser l'interaction complexe entre les mèches et les coutures, en tenant compte des mécanismes de glissement propre aux matériaux NCF. La crédibilité de notre modèle est attestée par des simulations de déformation en cisaillement dans le plan sur une cellule unitaire et des tests de cisaillement en bias-extension. Ces simulations mettent en évidence la polyvalence du modèle mésoscopique, permettant la caractérisation virtuelle des matériaux et réduisant les efforts expérimentaux généralement requis pour les simulations macroscopiques. De plus, notre approche offre des descriptions explicites des mèches et des coutures basées sur des observations en tomographie et générées à l'aide d'équations paramétriques. Cette fonctionnalité permet l'analyse de différents motifs de couture et de structures de tissu, offrant des opportunités de personnaliser les matériaux NCF avec un comportement de déformation optimisé pour des applications spécifiques. Conscient que le changement d'orientation des fibres influence considérablement le comportement mécanique de la pièce composite finale après l'étape de mise en forme, une méthode de post-traitement est proposée sur ce modèle mésoscopique pour suivre la direction des fibres et visualiser l'angle de cisaillement. Un avantage notable de notre approche de modélisation mésoscopique réside dans sa capacité à détecter et à analyser les défauts locaux, tels que le gapping, un défaut majeur dans la mise en forme des NCF difficile à observer directement via des simulations macroscopiques. Par conséquent, le modèle mésoscopique permet l'analyse et la prédiction de la formation et du développement des défauts du gapping, contribuant à améliorer la qualité et l'efficacité de la fabrication.
