• abstract = "This paper presents an aeroelastic characteristic of functionally graded graphene origami-reinforced auxetic metamaterial (FG-GORAM) composite laminated plates. The equivalent elastic parameters of each layer, including elastic modulus, Poisson's ratio, and density, are determined using the Halpin-Tsai model, modified through genetic programming (GP) and molecular dynamics (MD). The artificial boundary springs were introduced to simulate various boundary constraints, and the laminated plate's mathematical model was constructed using the first-order shear deformation theory (FSDT) coupled with first-order piston theory. The energy function of the FG-GORAM plate was derived based on Hamilton's principle, and the solution was obtained using the modified Ritz method. The accuracy and validity of the present method were confirmed through detailed convergence analysis and comparisons with the published literature data. Furthermore, extensive parametric analyses were conducted to examine the effects of boundary conditions, structural parameters of the plates, and different configurations of graphene origami. The results indicate that the flutter performance of FG-GORAM composite laminated plates is highly dependent on the boundary conditions of the plate and the different graphene origami configurations, including their distribution type, content, and folding degree. It is found that the FG-GORAM composite plate had better flutter performance than its plate without the addition of origami graphene. These findings provide a crucial theoretical foundation and technological guidance for the design of such advanced materials",
