利用 Neumann级数展开的 Monte- Carlo随机有限元法 ,分析了纤维缠绕壳体在内压及材料工程常数随机变化作用下的应力响应 ,绘出了最大应力响应分布曲线 ,为该类结构可靠性评估及可靠性设计提供了应力响应数字依据
Using Monte-Carlo stochastic finite element method developed by Neumann series, the stress response of fiber wound shell under the random variation of internal pressure and material engineering constant was analyzed. The maximum stress response distribution curve was plotted, Evaluation and reliability design provides a numerical basis for stress response
