Full TextAbstract
In this study, an analytical method is developed to analyze analytically displacements and stresses in a functionally graded composite beam subjected to transverse load. Assuming the functionally graded beam has nonhomogeneous mechanical properties in the thickness direction, the displacements and stresses of the beam are obtained based on a first-order shear deformation beam theory (FSDBT). The non-linear strain-displacement relations in the von Kármán sense are used to study the effect of geometric nonlinearity. Equilibrium equations are obtained by using the principle of minimum total potential energy and solved exactly. The results obtained from this method are compared with the finite element solution done by ANSYS. Numerical results of the first-order linear and non-linear theories are presented to show the effects of using FGMs instead of classical layered composites on the deflections and stresses.
