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 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...
متن کاملFinite dynamic deformations of smart structures
We study transient ®nite deformations of a neoHookean beam or plate with piezoelectric (PZT) patches bonded to its upper and lower surfaces. The constitutive relations for the PZTs are taken to be linear in the Green-Lagrange strain tensor but quadratic in the driving voltage. A ®nite element code using 8-noded brick elements has been developed and validated by comparing computed results with e...
متن کاملIdeal Homogeneous Access Structures Constructed from Graphs
Starting from a new relation between graphs and secret sharing schemes introduced by Xiao, Liu and Zhang, we show a method to construct more general ideal homogeneous access structures. The method has some advantages: it efficiently gives an ideal homogeneous access structure for the desired rank, and some conditions can be imposed (such as forbidden or necessary subsets of players), even if th...
