Thermo-elastic buckling behaviors of advanced fluid-infiltrated porous shells integrated with GPLs-reinforced nanocomposite patches

Abstract

In 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 of the fluids in the pores is investigated using Skempton coefficient. Imperfection types and ratio effects are also considered. Moreover, for the face layers, Graphene nanoplatelets (GPLs) weight fraction and dispersion patterns are studied. After deriving the governing equations employing virtual displacement method, they are solved analytically via Navier’s approach. Finally, the impact of different factors on the critical buckling loads (CBLs) and temperatures (CBTs) of cylindrical, spherical, and doubly-curved shells is assessed.
