this article gives an approach to predict the springbackward phenomena during post solidification cooling in a functionally graded hybrid composite cylindrical shell with transverse isotropic structure. here the material properties are considered to be given with a general parabolic power-law function. during theoretical analysis, appropriate transform is introduced in the equilibrium equation ...

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...

Functionally graded porous (FGP) plates have been introduced as modern structural members which open a new window to optimal and functional designs. Despite the need study effect of porosity on mechanical behavior FGP plates, it is necessary consider very extensive valuable literature in this field, presenting remarkable closed-form solutions. Hence, paper aims answer where possible implement a...

This paper presents a nonlinear vibration analysis of functionally graded graphene platelet (GPL) reinforced plates on elastic foundations. Uniformly or non-uniformly distributed internal pores were present in the plates. Based modified Halpin-Tsai micromechanics model and extended rule mixture, material properties evaluated. The governing equations, coupled with effect foundations, derived by ...

Functionally graded materials (FGMs) are composed of metals and ceramics in which the distribution material components varies according to a particular volumetric function. FGMs often used high-temperature applications. In our study, models were created Artificial Neural Network depending on equivalent stress levels compositional gradient exponent, is most important parameter determining thermo...

In this paper, the first-order shear deformation theory is used to derive theoretical formulations illustrating the nonlinear dynamic response of functionally graded porous plates under thermal and mechanical loadings supported by Pasternak’s model of the elastic foundation. Two types of porosity including evenly distributed porosities (Porosity-I) and unevenly distributed porosities (Porosity-...

This paper deals with the determination of displacement function and thermal stresses of a finite length isotropic functionally graded hollow cylinder subjected to uniform temperature field. The solution of the governing thermoelastic equation is obtained, as suggested by Spencer et al. for anisotropic laminates.  Numerical calculations are also carried out for FGM (Functionally graded material...

An approximate solution for the static analysis of three-dimensional, anisotropic, elastic plates composed of functionally graded materials (FGM) is presented. The solution is obtained by using a discrete layer theory in combination with the Ritz method in which the plate is divided into an arbitrary number of homogeneous and/or FGM layers. Two types of functionally graded materials are conside...

In this paper, the buckling and vibration behaviour of functionally graded flexoelectric nanobeam is examined. The vibration and buckling formulations of functionally graded nanobeam are developed by using a new theory that’s presented exclusively for flexoelecteric nano-materials. So by considering Von-Karman strain and forming enthalpy equation based on displacement, polarization and electric...
