This research explores the free vibration characteristics, both in-plane and transverse, of a circular plate made from functionally graded graphene origami-enabled auxetic metamaterial (GOEAM). An AI-assisted model is utilized to calculate micromechanical properties metamaterial. Three-dimensional linear elasticity theory formulate constitutive relations equations motion plate. By using two pairs transformation functions, these are transformed into couple independent state-space corresponding three-dimensional Graphene origami (GOri) platelets distributed with four different dispersion patterns along thickness. Also, folding degree GOri can vary. Two boundary condition types considered: elastic simple rigidly slipping. State-space solved through transfer matrix approach, frequency obtained for out-of-plane vibrations. The effects various parameters on frequencies GOEAM explored. findings indicate that incorporating highly folded enhances stiffness, more noticeable impact Distinct demonstrate peak natural transverse Although vibrations show declining trend, initially strengthens structure, resulting in higher before reaching maximum.
