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.
