An analytical approach for nonlinear thermo-mechanical buckling of functionally graded graphene platelet reinforced composite (FG-GPLRC) circular plates and shallow spherical shells resting on elastic medium using the higher-order shear deformation theory (HSDT) nonlinearities von Kármán is established in present work. Assuming that structures are axisymmetrically displaced central axis external pressure thermal loads applied. The used to model behaviour hardening or softening depending positive negative values parameter, respectively. By applying Ritz energy method, relation expressions load-deflection archived investigate postbuckling response critical load structures. Special effects with different stiffnesses, material parameters, geometrical dimensions explored discussed numerical results.

Stress wave propagation and free vibration response of functionally graded graphene platelet (FG-GPL)-reinforced porous joined truncated conical–cylindrical-conical shell are investigated in this paper. The is constructed a metallic matrix reinforced by three types distribution GPLs open-cell interior pores. modified Halpin–Tsai estimation the generalized rule mixture employed to calculate effective mechanical properties structure. Three different distributions for porosity assumed along with thickness: two kinds symmetric FG uniform porosity. Rayleigh-Ritz energy method, accompanied Finite element has been used solve 2D-axisymmetric elasticity equations. Furthermore, Newmark direct integration method applied obtain time responses stress shells subjected an internal impulse loading. A comparative detailed investigation also conducted indicate effects boundary conditions, geometries, weight fraction GPLs, coefficient, dispersion pattern on natural frequencies, mode shapes histories displacement stresses shell.

The present study investigates the free and forced vibration of composite nanoplate with an attached nano mass-spring-damper system. mentioned constitutes three layers in which core layer is assumed to be a functionally graded material, top bottom surfaces are supposed magneto-electro-elastic material. Eringen's nonlocal theory used consider small-scale effect, system rest Winkler Pasternak medium. Governing equations determined based on first-order shear deformation extended Hamilton's principle. Two coupled ordinary differential equation partial nanoplate's governing solved analytically aid Laplace Navier-type transforms. impact various parameters such as parameter, gradient index, magnitude mass, load velocity considered explained detail. research results indicate that increasing thickness increases natural frequency. To peruse study's precision efficacy, proposed compared articles accessible literature. existing investigation can drug delivery, biosensors, designing resonators.
