AN OVERVIEW OF FUNCTIONALLY GRADED MATERIAL MODELS

This paper presents an overview of functionally graded material models performed by the authors regarding functionally graded materials. Functionally Graded Materials (FGMs) represent a new material class belonging to the composite materials. We say that FGMs are composite materials because in different point of its thickness (beams, plates), the values of the elastic properties are varying according to a model. Our paper presents such a material models in a comparative way, by quantitative determinations and graphical representations. The analysis of these models of elastic properties allows us to obtain the properties we want (we need for a part or a structure). Conclusions upon the influence of an elastic property model are useful both in design, in manufacturing and in using of functionally graded materials.
