In this paper, based on the FE non-intrusive coupling framework, an innovative iterative global/local non-intrusive model coupling method was developed to analyze the local crack failure. Several acceleration strategies are studied to further reduce iterations. The FE simulation of a failure experiment of a joint structure is performed to verify the proposed method. Numerical results showed that the coupling results have very good convergence with experimental result.
