Smart Structures: Blurring the Distinction Between the Living and the Nonliving
Vinod K. Wadhawan
Abstract
A structure is an assembly that serves an engineering function. A smart structure is one that serves this function smartly, i.e., by responding adaptively in a pre-designed useful and efficient manner to changing environmental conditions. Smartness is normally associated with living beings, because they have the tendency to adapt themselves to changing situations. Artificial smart structures are designed to mimic biological structures to a small or large extent. This book gives a modern and comprehensive account of how this can be done. Adaptive behaviour of one or more materials constituting ... More
A structure is an assembly that serves an engineering function. A smart structure is one that serves this function smartly, i.e., by responding adaptively in a pre-designed useful and efficient manner to changing environmental conditions. Smartness is normally associated with living beings, because they have the tendency to adapt themselves to changing situations. Artificial smart structures are designed to mimic biological structures to a small or large extent. This book gives a modern and comprehensive account of how this can be done. Adaptive behaviour of one or more materials constituting a smart structure requires nonlinear response. This book describes the three main types of nonlinear-response materials: ferroic materials, soft materials, and nanostructured materials. Information processing by biological and artificial smart structures is also discussed. A smart structure typically has sensors, actuators, and a control and communication system. Progress in all these aspects of smart structures has leant heavily on mimicking Nature, and the all-important notion in this context has been that of evolution. Artificial Darwinian and Lamarckian evolution holds the key to the development of truly smart structures. Modestly intelligent robots are already on the horizon. Projections about the low-cost availability of adequate computing power and memory size indicate that the future really belongs to smart structures. This book covers in a compact format the entire gamut of concepts relevant to smart structures. It should be of interest to a wide range of students and professionals in science and engineering.
