Finite Element Analysis for the Static Response of Functionally Graded Porous Sandwich Beams
Özet
In this paper, the finite element method is used to analyze the static response of the functionally graded porous (FGP)
sandwich beams subjected to uniformly distributed loads along the beam span. The core of the beam is made up of functionally
graded porous material while the top and bottom layers are made up of isotropic homogenous materials. Uniform distribution
and symmetric distribution of pores are used as two different types of porous material. Shear deformation is considered in the
analysis by utilizing BEAM189 in ANSYS which is a finite element package program. This element is based on the first-order
shear deformation theory. The influence of porosity coefficient, boundary conditions, and type of the porous material on the
static response of the considered structures is presented in detail. The results demonstrate that the porosity coefficient has an
important impact on the static response of the FGP sandwich beams.
