Since the end of the 1980s, the concept of smart or intelligent materials and structures has become more and more present in the minds of engineers. These new ideas were particularly welcome in the fields of aerospace and civil engineering. The concept of Smart Materials/Structures can be consider as a step in the general evolution of man-made objects. There is a continuous trend from simple to complex in human production, starting from the use of homogeneous materials, supported by nature and accepted with their natural properties, followed by muti-materials in particular, composite materials, allowing us to create structures with properties adapted to specific uses.
