摘要: In this paper, the free vibration behavior of post-buckled functionally graded (FG) Mindlin rectangular microplates are described based on modified couple stress theory (MCST). This enables consideration size-effect through introducing material length scale parameters. The FG made a mixture metal and ceramic considered whose volume fraction components is expressed by power law function. By means Hamilton's principle, nonlinear governing equations associated boundary conditions derived for micro-plates in postbuckling domain. then discretized using generalized differential quadrature (GDQ) method before solving numerically pseudo-arclength continuation technique. solution procedure, problem investigated first. Afterwards, around buckled configuration discussed. effects dimensionless parameter, gradient index aspect ratio path frequency subject to arbitrary edge supports thoroughly
