| Abstract: | As a important form of connector and load-bearing structure, the connection property of composite bolted joint directly affect the structure reliability. Against the anisotropism and progressive damage character, the composite bolt and plate is modeled by finite element method. According to the written U-mat code, the progressive damage process of composite bolted joint is simulated by numerical method, the load-displacement curves of bolted joint are obtained, and the failure mode is studied in this paper. |
| Keywords: | Composite Joint Finite element method Progressive damage |
