In this study， the nonlinear buckling and postbuckling characteristics of composite microplates made of a porous functionally graded (PFG) material are scrutinized in the presence of different size-dependent strain gradient tensors as microscale。 Accordingly， for the first time， the effect of each microstructural tensor is analyzed separately on the nonlinear stability of PFG microplates with and without a central cutout。 In order to fulfill this goal， the isogeometric computation approach is engaged to integrate the finite element approach into the nonuniform B-spline-based computer aided design tool。 Accordingly， the geometry of the microplate with a central cutout is modeled smoothly to verify C-1 continuity based upon a refined higher-order plate formulations。 In this regard， the microstructural-dependent load-deflection paths associated with the nonlinear stability of axially compressed microplates are traced。
