Today, multi-functional materials such as
piezoelectric/ferroelectric ceramics, magneto-strictive and shape
memory alloys are gaining increasing applications as sensors,
actuators or smart composite materials systems for emerging high
tech areas. The stable performance and reliability of these smart
components under complex service loads is of paramount practical
importance. However, most multi-functional materials suffer from
various mechanical and/or electro-magnetical degra-dation
mechanisms as fatigue, damage and fracture. Therefore, this
exciting topic has become a challenge to intensive international
research, provoking the interdisciplinary approach between solid
mechanics, materials science and physics. This book summarizes the
outcome of the above mentioned IUTAM-symposium, assembling
contributions by leading scientists in this area. Particularly, the
following topics have been addressed: (1) Development of
computational methods for coupled electromechanical field analysis,
especially extended, adaptive and multi-level finite elements. (2)
Constitutive modeling of non-linear smart material behavior with
coupled electric, magnetic, thermal and mechanical fields,
primarily based on micro-mechanical models. (3) Investigations of
fracture and fatigue in piezoelectric and ferroelectric ceramics by
means of process zone modeling, phase field simulation and
configurational mechanics. (4) Reliability and durability of
sensors and actuators under in service loading by alternating
mechanical, electrical and thermal fields. (5) Experimental methods
to measure fracture strength and to investigate fatigue crack
growth in ferroelectric materials under electromechanical loading.
(6) New ferroelectric materials, compounds and composites with
enhanced strain capabilities.
