摘要: This paper presents an investigation on the nonlinear behaviors of nanocomposite cylindrical panels subjected to combined action uniform lateral pressure and compressive edge loads. The may rest elastic foundations be in a varying temperature environment. consists reinforcing carbon nanotubes either uniformly distributed (UD) or functionally graded (FG) along thickness direction panels. two cases bending initially compressed postbuckling pressurized are considered. A high-order shear deformation shell theory association with von Karman strain–displacement relationships is applied derive governing equations for nanotube reinforced composite (CNTRC) Furthermore, effects panel-foundation interaction variation also included analysis material properties CNTRC assumed temperature-dependent. Numerical results presented illustrate responses resting Pasternak-type foundations. present solutions highlight CNT volume fraction, rise, foundation stiffness as well initial stress
