The exploration of graphene has attracted extensive interest owing to its significant structural and mechanical properties. In this research, we numerically investigate wave propagation in defect-free single-layer graphene, considering geometrically nonlinear behavior through second-strain gradient elasticity. To capture the geometric nonlinearity, firstly, strain–displacement relations are introduced. governing equation associated boundary conditions derived using Hamilton's principle. Then, weak form, including element matrices, is established. eigenvalue problem solved for 2D periodic structures theory. Finally, dynamical properties such as band structures, mode shapes, energy flow, beaming effects analyzed. numerical results reveal that nonlinearity second strain influences characteristics graphene. findings contribute understanding graphene's dynamic response, with implications engineering applications graphene-based nanostructures.
