【 摘 要 】

In this paper, finite element model of muti-pin composite joint is established. Composite laminate of joint is treated as one whole plate. Matlab program is adopted to calculate equivalent material properties of composite laminate. Load distributions of single-lap composite joint are investigated, and simulation results show excellent agreement with experiments. Compared with FE model whose composite laminate material properties are given layer by layer, new FE model not only ensured calculation accuracy but also reduced model building time.
