One of the best effective nondestructive methods to predict buckling load imperfection sensitive thin-walled structures is vibration correlation technique (VCT). Although this can determine for conventional without reaching instability point, it still under development new and materials. Moreover, few studies have addressed analytical aspects VCT as revisited in literature review. This paper presents a novel formulation numerical investigation functionally graded porous nanocomposite cylindrical shells reinforced with graphene platelets (FGPNCS-R-GPLs) uniaxial load. In section, governing equations an axially loaded FGPNCS-R-GPLs are derived using modified Halpin–Tsai micromechanics approach, FSDT, Rayleigh-Ritz method. linear analysis, free nonlinear analysis axial load, performed. After validating models, obtained its result compared by results more reliability credibility. The demonstrate that maximum difference between predicted approach corresponding loads less than 3.5%. Furthermore, proposed provided good estimation especially when applied greater 73.8%
