Abstract |
|
Stress states of pre-stress filament wound parts are crucial to their design. However, proposed models exhibit certain errors that cannot be neglected. To minimize these errors, we propose an analytical model for tension-induced residual stress of composite rings with a metal liner based on elastic cylinder theory. The contributions of stress variation of inner layers on the entire part are calculated through inverse iteration method and the stress distribution of the outmost layer is accurately calculated by integral relationship. For comparisons with the analytical model, a finite element model is proposed based on several special simulation strategies. Both models are verified through winding experiments with the maximum error being under 5%. Compared with previous results of analytical models through three effect factors, the error between the two models in case of hoop stress was over 20%, thereby confirming the accuracy of our model. |
