In this work, a simple C° isoparametric higher‐order plate element is developed to study the free vibration analysis of bimodulus laminated plates. The eqriations of motion for the higher‐order plate theory are also derived variationally. The warping of cross section and transverse shear deformation are both considered. The natural frequencies and neutral surface locations are determined for benchmark problems. Compared with available analytical solutions, fast convergence and excellent agreement are observed for the present finite element formulation.
