This is the first research on smart control and frequency analysis of a cylindrical sandwich nanoshell in framework numerical-based generalized differential quadrature method (2D-GDQM). The current nanostructure made honeycomb core piezoelectric face sheets as sensor actuator (PFSA). For modeling size-dependent nanoshell, nonlocal stress-strain gradient theory (NSGT) presented. Also, this under conveying viscous fluid, related force calculated by modified formulation Navier–Stokes. structure rotates around its axial direction. stresses strains are obtained using higher-order shear deformation (HSDT). external voltage applied to layer, Proportional-Derivative (PD) controller used for output control. Governing equations boundary conditions implementing Hamilton's principle. results show that geometry core, PD controller, velocity fluid flow, length radius ratio (L/R), have significant influence characteristics nanoshell. Another important consequence applying leads an increase critical flow nanostructure.

This investigation focuses on the nonlinear behavior of porosity-dependent functionally graded (FG) truncated conical small-scale structures. The modified coupled stress theory, as well energy method, are applied to generate partial differential equations (PDEs) related buckling analysis simply supported nonuniform micro-cylindrical material dispersion is gradually changed along length structures between Nickel and concrete, while porosity voids scattered in radial direction, external radius structure decreases direction via mathematic applicable sports PDEs numerically solved generalized quadrature method (GDQM) with numerical iterative technique. In this particular context, aim predict results using a newly developed methodology that employs artificial neural networks (ANNs). predictions generated by approach will be compared against previously obtained data validated ensure their accuracy reliability. ANN expected provide more robust comprehensive framework for predicting results, which would helpful variety settings, from scientific research engineering applications.
