A numerical‐experimental approach to predict structural instability was developed to analyze thin composite tubes produced by filament winding subjected to external pressure. The divergence between mechanical properties characterized through standardized procedures and those of the manufactured component, influenced by imperfections and manufacturing peculiarities, was considered. A ring compression test and an inverse finite element analysis routine were used for material properties calibration. The routine was based on Tsai's master‐ply concept to deliver feasible constitutive properties values. Based on the numerical and experimental correlation, the implemented approach was considered effective and with good repeatability.

考虑制造参数和缺陷的复合管数值试验结构不稳定性分析

开发了一种预测结构不稳定性的数值实验方法来分析由细丝缠绕在外部压力下产生的复合管。考虑了通过标准化程序表征的机械性能与制造零件的机械性能之间的差异，这些差异受缺陷和制造特性的影响。环形压缩试验和逆有限元分析程序用于材料性能校准。该例程基于Tsai的母版概念来提供可行的本构特性值。基于数值和实验相关性，该实施方法被认为是有效的并且具有良好的可重复性。
