| 摘要: |
| The spinning technique has been widely used in the manufacture of aerospace thin-walled axisymmetric components because of its excellent formability. Damage and fracture， as the important defects that often occur and must be avoided in the forming and service stages of components， have attracted much attention of researchers. In this paper， the fracture behavior and laws of spinning components such as conical parts， tubular parts， and components with inner ribs are summarized， the typical coupled and uncoupled ductile fracture models are introduced， and their applications in spinning are analyzed. Meanwhile， the recent developments on the modified ductile fracture model in analyzing damage and fracture mechanisms of spinning are emphatically introduced. The results could provide guidance for the selection and establishment of appropriate ductile fracture models in the finite element simulation for the accurate prediction and analysis of fracture moment， location， form， damage mechanism， and evolution law， and help the development of precision spinning techniques for high-performance thin-walled complex components. |
