“…Given the tailormade characteristics of composite materials, functionally graded materials are also well known for this capability. In this latter type of composite, the constituents' mixture is ruled by mathematical expressions, which can either correspond to the designed composition evolution that one desires the materials to present or correspond to the one that those materials effectively present, as in the works [28,29].…”

This work aims to analyse the free-vibration response of functionally graded, simply supported beams with different gradient directions, taking into account nonlocal effects. To this purpose, the first-order shear deformation theory and the nonlocal elasticity theory of Eringen are used, in order to assess the influence of size dependency effects on the free-vibration responses of those beams. The influence of other factors such as the aspect ratio of the beams and the evolution of the constituents’ mixture through the beam thickness and along its length is also considered. In this last case, a mixture distribution is proposed, accounting for the boundary conditions’ characteristics. The finite element model is first verified against existing alternative solutions, to assess and illustrate its performance. Based on the conclusions achieved, a set of parametric studies is then developed. The results are discussed considering the material distribution profiles, and conclusions are drawn with respect to their relative performance under the analysed conditions.

Sandwich plates consist of a total of three layers with a thick core layer between two thin face layers. While the face layers provide resistance against bending, the core layer provides resistance against shear. General purpose finite element software programs are one of the most convenient and widely used analysis procedures for investigating the behavior of structures. Many design parameters can be easily examined by these analysis programs. In this study, the bending behavior of simply supported sandwich square plates on four sides with a ratio of core layer thickness to face layer thickness between 7 and 9 was investigated by using the general purpose finite element software program. The effect of the thickness change was investigated by changing the face and core layer thicknesses of the sandwich plates with a fixed total thickness. At the same time, the face and core materials were changed and the most suitable design in bending behavior was revealed. For this purpose, 110 analyzes were performed with 2 different face materials, 5 different core materials, 11 different thickness ratios, and the results were presented with graphics.
