Description
Electromagneto-Mechanics of Material Systems and Structures Electromagneto-Mechanics of Material Systems and Structures
Written by a leading expert, this book is a comprehensive introduction to the fundamentals and the state of the art in the electromagneto-mechanics of adaptive materials. Its varied topic range includes an overview on how electric, magnetic, and deformation fields interact with each other in the presence of advanced materials systems, such as electric conductors, dielectrics, ferromagnets, among others. Within this context, the author considers for each material system specific phenomena like vibrations, wave propagation, fracture, and fatigue. Readers will also gain a thorough understanding of applications in the electronics and nuclear energy industries, as well as in smart materials and MEMS.
Covers a wide and varied range of subject areas, spanning theoretical, experimental, computational studies as well as industrial applications
Features extensive applications in the electronics, nuclear engineering, smart materials and MEMS industries
Takes the reader from fundamental concepts, applied research, applications through to emerging technologies
Electromagneto-Mechanics of Material Systems and Structures is an all-in-one reference for advanced/graduate students in mechanical and electrical engineering, as well as materials science. It also serves as a handy refresher guide for engineers in related areas such as aeronautical and civil engineering.
