Abstract This research investigates the effects of cut-out on dynamic behaviour functionally graded carbon nanotube reinforced composite (FGCNTRC) plates. Finite element method (FEM) is utilized and SHELL181 type ANSYS Workbench 17.2 program utilized. To understand vibration characteristics FG plates, various shapes cut-outs such as triangular, square, rectangular, hexagonal, circular etc are c...

Abstract We use three-dimensional printing to manufacture lattices with uniform and graded relative density, made from a composite parent material comprising nylon matrix reinforced by short carbon fibers. The elastic–plastic compressive response of these solids is measured up their densification regime. Data experiments on the density are used deduce dependence homogenized constitutive in rang...

The work focuses on the post- buckling behavior of functionally graded graphene platelet (FG-GPL)-reinforced porous thick rings with open-cell internal cavities under a uniform external pressure. generalized rule mixture and modified Halpin–Tsai model are here used to evaluate effective mechanical properties ring. Three types porosity patterns assumed together five different GPL distributions a...

In the present paper, a novel unconstrained higher-order theory (UCHOT) is applied to analyse free vibration of cylindrical sandwich shells with nanocomposite face sheets reinforced graphene platelets. UCHOT considers shear and thickness deformations. It assumed that cylinder includes soft core which embedded between functionally graded platelets composites (FG-GPLRC). FG-GPLRC sheet consists s...

In the present study, silane-functionalized graphene (f-graphene)-reinforced chitosan nanocomposite films exhibiting enhanced mechanical properties have been prepared by the solution casting method. These nanocomposite films were characterized by X-ray diffraction, Raman spectroscopy and thermogravimetric analysis. In order to investigate the effect of silane functionalization, tensile tests we...

This paper presents the study on influence external pressures on vibration of functionally graded materials thin-walled cylindrical shell supported. The functionally graded materials (FGMs) properties are graded in the thickness direction of the shell. FGMs are advanced composite materials, consisting of different types of materials, in which the properties shift continuously from one material ...

functionally gradedpoisson’s ratio structures have been developed for critical protection. in thispaper, the static bending and buckling of fgpr nanoscale beam are studied basedon the nonlocal timoshenko beam model, in which both young’s modulus andpoisson’s ratio are assumed to vary continuously in the thickness direction. byutilizing total potential energy principle, equilibrium equations are...

free vibration of simply supported circular cylindrical shell made of functionally graded material (fgm) under internal pressure was investigated. the effective material properties are assumed to vary continuously along the thickness direction according to a volume fraction power law distribution. first order shear deformation theory based on love's first approximation theory was utilized in th...

this paper deals with volume fraction optimization of functionally graded (fg) beams resting on elastic foundation for maximizing the first natural frequency. the two-constituent functionally graded beam consists of ceramic and metal. these constituents are graded through the thickness of beam according to a generalized power-law distribution. one of the advantages of using generalized power- l...
