In this paper, both 2D and quasi-3D hyperbolic integral shear deformation theories are employed for buckling analysis of functionally graded (FG) plates. The simplicity the developed theory is due to reduced number unknowns used in field displacement. proposed model takes into account effect normal transverse deformations ensures nullity stresses at top bottom surfaces studied structure without...

Abstract In this study, the first-order shear deformation theory (FSDT) is used to establish a nonlinear dynamic model for conical shell truncated by functionally graded graphene platelet-reinforced composite (FG-GPLRC). The vibration analyses of FG-GPLRC are presented. Considering platelets (GPLs) with three different distribution patterns, modified Halpin-Tsai calculate effective Young’s modu...

This paper presents a clear monograph on the optimization of thermal instability resistance of the FG (functionally graded) flat structures. For this aim, two FG flat structures, namely an FG beam and an FG circular plate, are considered. These structures are assumed to obey the first-order shear deformation theory, three-parameters power-law distribution of the constituents, and clamped bounda...

The application of B-spline wavelet on the interval (BSWI) finite element method for static, free vibration and buckling analysis in functionally graded (FG) beam is presented in this paper. The functionally graded material (FGM) is a new type of heterogeneous composite material with material properties varying continuously throughout the thickness direction according to power law form in terms...

A functionally graded (FG) material system is employed to make fiber use more efficient in a fiber reinforced cement composite (FRCC). This preliminary study demonstrates beam elements that were functionally graded fiber reinforced cement composite (FGFRCC) with four layers, each with a different fiber volume ratio. Fiber volume ratio was graded in accordance with its potential contribution to ...

We analyze plane strain static thermoelastic deformations of a simply supported functionally graded (FG) plate by a meshless local Petrov–Galerkin (MLPG) method. Material moduli are assumed to vary only in the thickness direction. The plate material is made of two isotropic randomly distributed constituents and the macroscopic response is also modeled as isotropic. Displacements and stresses co...

Based on the classical shell theory, the linear dynamic response of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) truncated conical shells resting on elastic foundations subjected to dynamic loads is presented. The truncated conical shells are reinforced by single-walled carbon nanotubes (SWCNTs) that vary according to the linear functions of the shell thickness. The motio...

The widespread use of structural elements consisting functionally graded (FG) materials in advanced technologies has led to extensive research. Due the difficulties encountered during modeling and problem solving, number studies on dynamic behavior made FG viscoelastic is quite limited compared examining elastic materials. This study one first attempts solve dynamical by mathematical plates (FG...

in this paper, the influence of the constituent volume fractions by changing the values of the power-law exponent with uniform pressure on the vibration frequencies of reinforced functionally graded cylindrical shells is studied. the fgm shell with ring is developed in accordance to the volume fraction law from two constituents namely stainless steel and nickel. these constituents are graded th...
