Experimental and numerical studies on the mechanical response of a piezoelectric nanocomposite-based functionally graded materials
Abstrakt
This work presents an experimental study of piezoelectric structures reinforced by graphene platelets, based on the concept of the functionally graded materials (FGMs). The assumed model is a rectangular beam/plate and the composition is due to the Halpin-Tsai rule. The model is also simulated in the Abaqus software which is the first time that such a structure has been modelled in an FEM package. In addition, a mathematical model based on a beam/plate theory, Lagrangian strains and variational technique is expressed and the derived partial differential equations governing the mechanics of the structure are solved numerically using the differential quadrature method. In terms of the experiments, the nanocomposite is fabricated in the form of layered FGMs using powder metallurgy. The specimens are subjected to two mechanical tests, bending and tensile. To accurately identify the FGM sample cross-section, a scanning electron microscope is used to examine the microstructure of the solid.
