Abstract:
This paper enumerated ubiquitous natural layered materials and artificially layered materials from different fields, such as geography, biology, environment, materials, chemistry and physics, illustrating the extensive existence of layered structures. It has been found that in the high-tech frontier areas, more and more new materials adopt layered structure (such as grapheme, organic solar cells, aviation composites and biomimetic materials)in order to achieve multi-function integration; at the same time, it has been also found that although there are a variety of layered structures, they all objectively have the characteristics of continuity of specific parameters (such as displacement, sound pressure and stress, etc.) on the interlayer interface and recursive influence of each layer in turn. Therefore, for any multi-layered structure in any field, it is an important and fundamental problem to build a universal mathematical model that can reflect these features so as to study its internal correlation and comprehensive overall performance. In this paper, a preliminary discussion has been made on this and the basic framework of the universal model has been established.
