The natural frequency and the transient responses of Carbon/Epoxy layered composite plate structure have been analysed with the help of two higher-order mid-plane kinematics models in this article. The mathematical formulation of the layered composite structure is further utilised to develop a computer programme in MATLAB-15.0, to evaluate the said responses. The practical relevance of the present higher-order models has been established via comparing the present numerical results computed using suitable MATLAB computer code with the in-house experimental test data. Additionally, the fundamental frequency and the transient responses of the carbon fibre reinforced epoxy composite plate structure are simulated via finite element package (ANSYS) with the help of ANSYS parametric design language (APDL) code. The simulated frequencies are compared with those of the present experimental and MATLAB results. Finally, the significance of the proposed higher-order kinematics has been established via solving a different kind of illustrations to investigate the influence of various geometrical and material parameter on the dynamic responses of layered composite structure and discussed in detail.
