【 摘 要 】

In this paper, finite element model of multi-pin composite joint is established. Matlab program is adopted to calculate equivalent material properties of composite laminate. Load distributions of double-lap composite joint are investigated, and simulation results show excellent agreement with experiments. By using equivalent material properties method, influence of stacking sequence on load distribution is studied. Equivalent material properties method could provide a simple and efficient method for optimizing load distribution of multi-pin composite joint.
