Smart materials and structures.
A smart structure is a system containing multifunctional parts that can perform sensing, control, and actuation; it is a primitive analogue of a biological body. Smart materials are used to construct these smart structures, which can perform both sensing and actuation functions. The ‘‘I.Q.’’ of smart materials is measured in terms of their ‘‘responsiveness’’ to environmental stimuli and their ‘...
متن کاملMathematical modelings of smart materials and structures
We aim to present mathematical models of smart materials and smart structures. Smart materials are materials which present significant multiphysical couplings. They are integrated in smart structures which take technological advantages of some multiphysical effects. We establish a classification of piezoelectric crystalline materials and propose simplified but accurate models of thin plates or ...
متن کاملVibration Suppression: Reduced-order Model/residual Mode Filter Control Using Smart Structures - Aerospace Conference, 1998 IEEE
For spacecraft with large flexible antennas, andor flexible support structures, suppressing vibrations caused by on-orbit operational disturbances (e.g., antenna slew maneuvers and thruster firings) is a challenging problem. In the past several years, advances in smart structure technologies have made their use in real-time dynamic control cif a structure possible. This paper discusses analytic...

متن کاملSmart Materials, Precision Sensors/Actuators,Smart Structures, and Structronic Systems
Many electroactive functional materials have been used in smalland microscale transducers and precision mechatronic control systems for years. It was not until the mid-1980s that scientists started integrating electroactive materials with large-scale structures as in situ sensors and/or actuators, thus introducing the concept of smart materials, smart structures, and structronic systems. This p...
