An energy method for buckling behavior analysis of functionally graded carbon nanotube-reinforced composite sandwich structures

Abstract The present work aims to investigate the buckling performance of sandwich structure functionally graded carbon nanotube-reinforced composite (FG-CNTRC). Through first-order shear deformation theory, an analytical model for FG-CNTRC was established. governing equation prediction obtained through energy method. There solution that can satisfy both boundary conditions. theoretical and method were verified by literature analysis, influence each parameter on evaluated performed basis corroborated model. findings lay a solid foundation design application FG-CNTRC.
