This study investigates the vibrational behavior of three-phase polymer-glass fiber (FG)-carbon nanotubes (CNT) nanocomposites conical panels. Effects wavy shape CNTs and viscoelastic nature polymer matrix are considered. First foremost, equivalent material properties estimated in context a three-step hierarchical approach. Then, governing equations attained by combining first-order shear deformation theory (FSDT) Hamilton's principle. Furthermore, Ritz method is employed to extract frequency responses with help Chebyshev polynomials for both simply supported clamped ends For parametrical studies, effect different geometrical constraints, instance, effects relaxation time considering waviness coefficients CNT, reported. The findings this paper reveal significant on estimation dimensionless frequency. under boundary conditions parameter 60 s, structure reduces approximately 23% after 100 s.

The present article deals with the application of refined plate theory and surface effects to investigate nonlocal free vibration behavior a functionally graded nano-plate composed two piezoelectric face sheets resting on Orthotropic Visco-Pasternak. Surface are applied using piezoelectricity stress-strain gradient theories. effects, quasi-3D higher-order theory, neutral position in-plane mechanical preloads considered study sandwich core in this for first time, simultaneously. size-dependent governing equations derived based 2D 3D Hamilton's principle different boundary conditions studied investigated according semi-analytical solution method. Comparing results models, local non-local also, examining foundations simultaneously can be said as one innovations current research. Finally, parametric is presented examine parameters such small scale parameters, preloads, thickness stretching position, non-homogeneous coefficient, voltage, foundation constants, conditions, geometrical ratios theories details. It indicated that inclusion leads significant influence three-layered nano-scale plates. may provide useful guidance design development next generation nano-devices.
