| Abstract: | Forming principle and parameter determination of Jones Nelson Morgan Model are expounded. The nonlinear constitutive relations of filament wound composites are studied with J N M model. The large deformation formulae of filament wound case (FWC) are derived, and the finite element model of the FWC is established. The large deformation of the FWC under internal pressure loads is analyzed. Combining material nonlinearity with large deformation, the computational results of the FWC have been obtained. The results are better than those of considering only large deformation, and it is in good agreement with test data. |
