Ouyang, X., 2020. Finite element free vibration analysis of marine composite laminates with variable stiffness. In: Yang, D.F. and Wang, H.

Reinforced variable stiffness composites are commonly used in marine engineering and marine engineering structures. The free vibration behavior of composite laminates varies with varying stiffness. Classical layering theory and first-order shear deformation theory are used to model the structure. On the basis of the virtual work principle and the finite element method, the vibration equation is established. The curved fiber can improve the design performance of composite laminates, and the free vibration behavior of composite laminates with variable stiffness can be changed by changing the orientation of the fiber.
