AbstractIn the existing paper, thermo-mechanical buckling performance of three-layered advanced fluid-infiltrated porous shells that are embedded between two GPLs-reinforced composite layers is investigated. The influence fluids in pores investigated using Skempton coefficient. Imperfection types and ratio effects also considered. Moreover, for face layers, Graphene nanoplatelets (GPLs) weight fraction dispersion patterns studied. After deriving governing equations employing virtual displacement method, they solved analytically via Navier's approach. Finally, impact different factors on critical loads (CBLs) temperatures (CBTs) cylindrical, spherical, doubly-curved assessed.Keywords: nanoplateletsfluid-infiltrated materialsthermo-elastic bucklingfirst-order shear deformation theorydoubly-curved shellsandwich structures Disclosure statementThe authors state there no conflict interest them to disclose.

Lately, metal foams have been widely used in various engineering structures due to their exceptional mechanical properties, including lightweight. However, scientists proposed adding nano-fillers like graphene nanoplatelets (GNPs) overcome the issue of low stiffness caused by increased porosity. Hence, aerodynamic stability and vibrational behaviors nanocomposite (NCMF)-reinforced GNPs sector microplate with piezoelectric/metallic face sheets are provided this work. The microstructure is sited on Kerr elastic substrate also a hygro-thermo-electrical media, subjected supersonic flow based first-order piston's theory (FPT). Gaussian random field (GRF), Halpin-Tsai, extended rule mixture (ERM) conjunction Gurtin-Morduch, modified strain gradient theories, Hamilton's principle derive governing equations linked boundary conditions. Generalized differential quadrature (GDQ) scheme chosen attain results. By validating results' precision, effects different parameters natural frequencies (NFs) critical pressures (CAPs) observed. It perceived that enhances both NFs CAPs significantly, increasing porosity up seventy percent, leads results drop. Various industries use simpler models evaluate microstructure, therefore present model can pave way for future uses push boundaries knowledge these it produces.

Flexoelectricity indicates a unique characteristic of insulators and dielectric materials that results in electrical polarization induction response to the non-uniform strain gradient. The impact this property is bolder on microscale nanoscale rather than macroscale. This article conducted derive governing equations motion for flexoelectric-multilayer structure evaluate its vibrational behavior various variable variations. model includes functionally graded (FG) porous core which confined between two flexoelectricity-based face sheets at both sides Vlasov type foundation. To gain equations, new power law material beside Hamilton's principle (HP) modified couple stress theory (MCST) implemented. Capturing effects length scale parameter, different materials, aspect thickness ratios, porosity index, foundation parameter boundary conditions (B.C.s) normalized natural frequency (NNF) such multilayer based novel FG formulation serve as main novelty article. According results, it revealed lateral ratio enhancement causes NNF stiffness reduction model. Furthermore, among all considered B.C.s, simply support (SSSS) clamped (CCCC) refer lowest highest respectively. content recent serves good source provide better understanding high stiffness-to-weight structures
