The couple stress theory is a non-classical continuum theory which is capable to capture size effects in small-scale structures. This property makes it appropriate for modeling the structures in micron and sub-micron scales. The purpose of this paper is the derivation of the governing motion equations and boundary conditions for the geometrically nonlinear micro-plates with arbitrary shapes based on the modified version of the couple stress theory. The consistent boundary conditions are provided at smooth parts of the plate periphery and also at the sharp corners of the periphery using variational approach.
► Geometrically nonlinear couple stress based microplate formulation is presented.
► Governing equations of motion together with boundary conditions are derived.
► The periphery of the plate can be in any arbitrary shape including corners.
