abstract

In this paper it is proposed a theoretical model of an ‘intelligent material’ system. An ‘intelligent material’ body is seen as a flexible body capable to manage energy, deformations and information. In any finite element dynamical, material and information processing properties are coexisting and interacting. On the basis of some Shannon and Kolgomorov theory and network statistical physics relations, it is shown how such a material is actually able to store and process information in itself physical structure. Some relations linking the dynamical characteristics to the information metrics are shown. A finite element model for intelligent materials is outlined. The aim of this approach is, on one side, to explain why the payload ratio of, for example, an human arm is much higher than that of a (current) robotic arm, on the other end, to suggest that deeper relations between material dynamics computational models, information and control theory could help design new artifacts with new improved performance, closer to what we can see in natural biological examples.
