| Abstract: |
| Analyzed the stress response under the action of gas pressure according to random variation for the fiber winding shell of a solid rocket motor by using the method of Monte Carlo stochastic finite element and combining with shell mechanics and fiber winding theory of composite material.The curves of stress distribution were given,which laid a foundation for the reliability estimation of solid rocket motor structure |
| Key words: Rocket engine case Filament winding Monte Carlo method Finite element method Structural response |
