Piezo-active Composites: Orientation Effects and Anisotropy Factors

The book is devoted to the problem of microgeometry properties and anisotropy relations in modern piezo-active composites. These materials are characterized by various electromechanical properties and remarkable abilities to convert mechanical energy into electric energy and vice versa. Advantages of the performance of the composites are discussed in the context of the orientation effects, first studied by the authors for main connectivity patterns and with due regard to a large anisotropy of effective piezoelectric coefficients and electromechanical coupling factors. The novelty of the book consists in the systematization results of orientation effects, the anisotropy of piezoelectric properties and their role in forming considerable hydrostatic piezoelectric coefficients, electromechanical coupling factors and other parameters in the composites based on either ferroelectric ceramic or relaxor-ferroelectric single crystals.

Topolov have been published in “Dictionary of International Biography” (IBC, Cambridge, UK), “2000 Outstanding Intellectuals of the 21st Century” (IBC, Cambridge, UK) and “Who’s Who in the World” (Marquis, New Providence, USA).

Paolo Bisegna was born on June 13th, 1968. He received the M.Sc. degree in engineering from the University of Naples “Federico II”, Naples, Italy, in 1991, and the M.Sc. degree in mathematics from the University of Rome “Tor Vergata”, Rome, Italy, in 1994, where he received the M.D. degree from the School of Medicine in 2006. He is a Professor of Mechanics in the Department of CivilEngineering, University of Rome “Tor Vergata”. He has been a visiting scholar at the Department of Mathematics, Vanderbilt University, Nashville, TN, USA. His research interests include piezoelectric composites, smart materials, ferroelectric ceramics and composites for modern sensors and actuators. He has published approximately 100 scientific papers and conference proceedings, including a chapter in a monograph published at Nova Science Publishers (New York, USA, 2011).

Christopher Rhys Bowen was born on January 18th, 1968 and grew up in Beddau, South Wales (UK). He earned a BSc (First Class) in Materials Science at the School of Materials, University of Bath, UK in 1990 and worked on his DPhil thesis in ceramics under the supervision of Prof. Brian Derby in the Department of Materials, University of Oxford, UK in 1990–1993 (PhD awarded in 1994). In 1993–1994, he worked as a Researcher in the Advanced Ceramics Group at the Technical University of Hamburg-Harburg (TUHH), Germany under the supervision of Prof. Nils Claussen. From 1994 to 1996, he was research fellow at the School of Materials, University of Leeds, UK. From 1996 to 1998, he was a Senior Scientist at DERA, Functional Materials Group, UK. He joined the University of Bath in August 1998 and is now a Professor at the same University.
