In this article, the two-way coupled thermoelastic behavior of axially graded composite plate and doubly-curved (cylindrical, spherical, hyperbolic, elliptical) panels is examined under conductive-convective boundary uniformly distributed loading conditions. Here, material properties axial functionally panel are computed by employing power-law-based Voigt's scheme. The geometric nonlinearities incorporated using cubic-polynomial-based temperature-dependent constitutive model higher-order kinematics-based Green-Lagrange strain, respectively. temperature profile obtained through thermally nonlinear theory associated with high temperature, which used to extract energy equations from first law thermodynamics deformation-dependent entropy relation. weak forms motion heat-transfer derived Galerkin's method further combined into field equation 2D-finite element approximation via Lagrangian elements. transient responses Newmark Crank-Nicolson schemes, whereas iterations executed Picard's iteration technique. performance fully for an (metal/ceramic) structure verified analytical, numerical, experimental results tested a variety numerical illustrations various sets

The manuscript aims to perform the free and forced vibration analysis considering porosity orthotropic foundation effect. For first time, study is conducted on a variable thickness FGM plate resting an foundation. This uses first-order shear deformation theory (FSDT) model present exact solution for of functionally graded material (FGM) with thickness. plate, having exponentially varied properties in direction, was restrained simply supported (S-S-S-S) clamped-clamped (C-C-C-C) boundary conditions. Three different types microstructural defects (porosity) are taken into consideration during establishment mathematical modeling. In addition, effect Pasternak has been incorporated formulation. governing differential equation thick thin plates derived using variational approach, further, Galerkin method applied solve motion. results have compared validated existing literature available rectangular elastic parametric studies done explore detailed understanding E-FGM (Exponentially material) including defects.

Abstract In this study, the post‐buckling damage behavior of cylindrical composite tubes was examined experimentally. The samples were reinforced with glass, carbon, and kevlar fibers to obtain glass‐reinforced fiber polymer (GRFP), carbon‐reinforced (CRFP), Kevlar‐reinforced (KRFP) tubes. produced using 4 stacking layers filament winding technology. producing all tubes, outer diameter kept constant at 17 mm, two inner diameters 12 13 wall thicknesses, 5 angles, lengths used as parameters. load applied until completely damaged, maximum values obtained measured on testing device. effect different reinforcement materials, angle, thickness, length load‐carrying capacity analyzed it understood that they had a significant effect.

AbstractThe dynamic response of viscoelastic plates reinforced with functionally graded carbon nanotube-reinforced composite material (FG-CNTRC) under loads was examined in this work. This research investigates the analysis CNTRC by single-walled CNTs (SWCNTs). SWCNTs were considered to be straight and aligned, a homogeneous pattern. Carbon nanotube (CNT) configurations investigated, inclusive uniform, three varieties FG distributions across thickness. The equation motion obtained using Hamilton's principle. time-dependent equations derived applying Navier solution method motion. These converted into Laplace domain. Modified Durbin procedure used convert resultant computations from field time field. resulting findings compared other methods. It demonstrated that are consistent those Then, sensitivity revealed CNT volume fractions, damping ratios, had substantial influence on quasi-static behavior FG-CNTRC plates. Results show help technique no need use free vibration frequencies or modes, it is possible solve problem quite precisely, effectively, easily.Keywords: Dynamic analysisviscoelastic dampingFG-CNT materialLaplace transformDurbin's Disclosure statementNo potential conflict interest reported author(s).Additional informationFundingThis received specific grant any funding agency public, commercial, not-for-profit sectors.
