Smart Structures: Physical Behaviour, Mathematical Modelling and Applications (Hardcover)

Synthesizing knowledge acquired as a result of significant research and development over recent years, Smart Structures clearly illustrates why these structures are of such intense current interest. Gaudenzi offers valuable insight into both how they behave and how and at what cost they could be designed and produced for real life applications in cutting edge fields such as vibration control, shape morphing, structural health monitoring and energy transduction.

 

Smart Structures offers a basic and fundamental description of smart structures from the physical, mathematical and engineering viewpoint. It explains the basic physics relating to the behaviour of active materials, gives the mathematical background behind the phenomena, and provides tools for numerical simulation. It also offers an insight into considerations related to the manufacturing, assembly and integration of smart structures.

 

Smart Structures is divided into 5 sections: in the first part a definition of smart structures is proposed, the motivation for developing a smart structure presented and the basic physics of active materials such aspiezoelectrics, electrostrictives, magnetostrictives and shape memory alloys briefly recalled. A second part is devoted to the mathematical modelling of piezoelectric bodies. The third part discusses actuation and sensing mechanisms based on which the active part of a smart structure will produce “results” on the passive one. The fourth part deals with active composites at the micromechanical and macromechanical level, and the fifth part is devoted to applications of smart structures with examples taken from the aerospace field.

 

This introduction to smart structures will be useful both for structural and mechanical designers, and for students and researchers at graduate level or beyond. The diverse industries involved in this rapidly evolving field include aerospace, automotive and bioengineering.

透過近年來的大量研究和開發所獲得的知識，智慧結構清楚地說明了為何這些結構如此引起當今濃厚的興趣。Gaudenzi提供了有價值的洞察，闡述了它們的行為方式，以及如何以及以何種成本在實際應用中設計和製造，應用於振動控制、形狀變換、結構健康監測和能量轉換等尖端領域。

 

智慧結構從物理、數學和工程的角度提供了對智慧結構的基本和基礎描述。它解釋了與活性材料行為相關的基本物理學，提供了現象背後的數學背景，並提供了數值模擬的工具。它還提供了有關智慧結構製造、組裝和集成的相關考慮。

 

智慧結構分為5個部分：第一部分提出了對智慧結構的定義，介紹了發展智慧結構的動機，並簡要回顧了壓電材料、電致伸縮材料、磁致伸縮材料和形狀記憶合金等活性材料的基本物理學。第二部分專門討論了壓電體的數學建模。第三部分討論了基於此的作用和感測機制，這些機制使智慧結構的活性部分對被動部分產生“結果”。第四部分涉及微觀和宏觀層面的活性複合材料，第五部分則專門介紹了智慧結構的應用，並以航空航天領域的例子為例。

 

這本介紹智慧結構的書籍對結構和機械設計師以及研究生及以上的學生和研究人員都很有用。參與這個快速發展領域的多個行業包括航空航天、汽車和生物工程。
