| Abstract: | A structure is an assembly that serves an engineering function. It is reasonable to expect that all engineering design should
be smart, and not dumb. But one can still make a distinction between smartly designed structures and smart structures. The
latter term has acquired a specific technical meaning over the last few decades. A smart structure is that which has the ability
to respond adaptively in a pre-designed useful and efficient manner to changes in environmental conditions, including any
changes in its own condition; the response is adaptive in the sense that two or more stimuli or inputs may be received as
anticipated and yet there is a single response function as per design. Smartness ensures that the structure gives optimum
performance under a variety of environmental conditions. While structures with some degree of smartness have been designed
from times immemorial, the current activity and excitement in this field derives its impetus from the level of sophistication
achieved in materials science, information technology, measurement science, sensors, actuators, signal processing, nanotechnology,
cybernetics, artificial intelligence, and biomimetics. |
