Introduction In materials science, composite laminates are assemblies of layers of fibrous composite materials which can be joined to provide required engineering properties, including in-plane stiffness, bending stiffness, strength, and coefficient of thermal expansion.
It is known that composite laminated plates have wide applications in many engineering structures, especially in the aeronautics industry and launch vehicles.
When the engineering structure with composite laminated excited will undergo the complex nonlinear oscillations of large amplitude, which can result in the geometrically nonlinear problem.
