A Partial-Periodic Model for Predicting Structural Stiffness of Composite Laminate Beam Structures
A partial-periodic model is proposed for predicting structural properties of composite laminate structures. The partial-periodic model contains periodic boundary conditions in one direction or two directions, and free boundary condition in other directions. In the present study, partial-periodic model for composite laminate beam structures is particularly studied. Three-point bending experiments for laminate beam specimens with different laying parameters are firstly used to verify the present partial-periodic model. In addition, a detailed finite element method (FEM) model is also used to further quantitatively compare with the present partial-periodic model for composite laminate beams with different laying parameters. The results indicate that the proposed partial-periodic model is capable of providing accurate predictions in most cases. The computational time cost of the proposed partial-periodic model is much lower than that of the detailed FEM model as well. Convergence studies are also conducted for the present partial-periodic model with different model sizes and element sizes. It is suggested that the proposed partial-periodic model has the potential to be used as an accurate and time-saving tool for predicting the structural properties of composite laminate beam structures.
