Nonlinear buckling analysis of higher-order shear deformable FG-CNTRC plates stiffened by oblique FG-CNTRC stiffeners

The nonlinear buckling analysis of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) plates subjected to axial compression load is analytically examined in this paper. Assuming that the FG-CNTRC are stiffened by an oblique stiffener system. Reddy’s higher-order shear deformation plate theory (HSDPT) with geometrical nonlinearities von Kármán applied establish basic formulations. Moreover, smeared technique successfully improved for deformable anisotropic system using a homogeneous model beam. Galerkin’s method used achieve expressions critical loads and postbuckling load-deflection curves explicit form. numerical values display influences stiffeners, material, properties on response plates.
