Modelling of FGM plate

Grzegorz Jemielita, Zofia Kozyra
The paper presents formulation of the problem of layered plates composed of two various
isotropic materials. We assume that the first material M1 is characterized by the following
parameters: Young’s modulus E1 and Poisson’s ratio 1, whereas the second one by E2 and
2, respectively. Let us consider two modelling cases for functionally graded material (FGM)
plates. These cases are related to an appropriate distribution of the material within two-layer
and three-layer systems. Our objective is to compare the stiffness of both the two-layer and
there-layer plates with the FGM plate containing various proportions between the material
components M1 and M2.
Keywords: modeling, layer plate, FGM plate, stiffness of the plate
