This book presents a mechatronic approach to Active Noise Control (ANC). It describes the required elements of system theory, engineering acoustics, electroacoustics and adaptive signal processing in a comprehensive, consistent and systematic manner using a unified notation. Furthermore, it includes a design methodology for ANC-systems, explains its application and describes tools to be used for ANC-system design. From the research point of view, the book presents new approaches to sound source localization in weakly damped interiors. One is based on the inverse finite element method, the other is based on a sound intensity probe with an active free field. Furthermore, a prototype of an ANC-system able to reach the physical limits of local (feed-forward) ANC is described. This is one example for applied research in ANC-system design. Other examples are given for (i) local ANC in a semi-enclosed subspace of an aircraft cargo hold and (ii) for the combination of audio entertainment with ANC.
This careful and detailed introduction to non-linear continuum mechanics and to elasticity and platicity, with a unique mathematical foundation, starts right from the basics. The general theory of mechanical behaviour is particularized for the broad and important classes of elasticity and plasticity. Brings the reader to the forefront of today's knowledge. A list of notations and an index help the reader finding specific topics.
Das Buch bietet einen besonders studierendenfreundlichen Zugang zur Spannungs- und Verformungsberechnung von Leichtbaustrukturen des Fahrzeug- und Flugzeugbaus. Aufbauend auf den Grundlagen der Festigkeitslehre wird insbesondere die Schubspannungsberechnung infolge von Torsion und Querkraft vertieft. Im Leichtbau verwendete mechanische Modelle sowie leichtbautypische Näherungen werden bzgl. ihrer Geltungsbereiche untersucht. Darüber hinaus werden Arbeits- und Energiemethoden sowie die Stabilitätstheorie für Leichtbaustrukturen detailliert behandelt. Abschließend wird das Erlernte zur Entwicklung der Modelle Schubwand- und Schubfeldträger genutzt und mögliche Anwendungsfälle dargestellt. In jedem Kapitel wird in das behandelte Thema anschaulich eingeführt und darauf aufbauend die Theorie erläutert. Die Anwendung dieser Theorie wird anhand ausführlich durchgerechneter Beispiele vermittelt. Jedes Kapitel enthält eine Zusammenfassung, die als Nachschlagewerk genutzt werden kann, sowie einen Fragenkomplex zur Lernstandskontrolle. Infoboxen zu Persönlichkeiten mit bedeutendem Einfluss auf das Gebiet Mechanik lockern die Kapitel auf und runden die Themen ab.

Dynamic Mechanical and Creep-Recovery Behaviour of Polymer-Based Composites: Mechanical and Mathematical Modeling covers mathematical modelling, dynamic mechanical analysis, and the ways in which various factors impact the creep-recovery behaviour of polymer composites. The effects of polymer molecular weight, plasticizers, cross-linking agents, and chemical treatment of filler material are addressed and information on thermoplastic and thermosetting polymer-based composites is also covered, including their various applications and the advantages and disadvantages of their use in different settings. The final 2 chapters of the book cover mathematical modeling of creep-recovery behavior for p...
Expanded PTFE Applications Handbook: Technology, Manufacturing and Applications is a comprehensive guide to ePTFE, explaining manufacturing technologies, properties, and applications. Technologies that were previously shrouded in secrecy are revealed in detail, as are the origins and history of ePFTE. The book is an essential handbook for scientists and engineers working in PTFE processing industries, and for manufacturers working with fluoropolymers. It is also of use to purchasing managers and academics. - Presents every aspect of the manufacturing technologies and properties of ePFTE - Provides detailed coverage of ePTFE applications in apparel, medical, and surgical devices, filtration, vents, and industrial uses - Follows ePFTE from its original discovery to the latest developments
Includes supplementary volumes called Ergänzungsbände and Sonderbände covering work published during and after World War II through 1954 and not abstracted in Chemisches Zentralblatt volumes for that period.
