摘要

本文研究了一种考虑纤维缠绕过程中纤维波动的纤维缠绕管模型。采用有限元方法对模型进行了线性分析，并与壳体模型和径向破碎实验进行了比较。结果表明，由于包含纤维波动特征，实体模型比壳模型具有更高的径向压缩刚度预测精度。该模型是开发复合材料压力容器模型的第一步，其中纤维波动更频繁，也可用于预测失效启动和损伤传播。

Modeling the influence of fiber undulation in a filament-wound composite tube under radial crushing load

This study investigates a filament-wound tube model incorporating fiber undulation from the filament winding process. The model was analyzed using the finite element method in the linear regime, then compared with the shell model and radial crushing experiment. Results showed that the solid model predicts the radial compression stiffness with a higher level of accuracy than the shell model due to the inclusion of the fiber undulation feature. This model is a first step towards the development of a composite pressure vessel model where fiber undulation is more frequent, and also for predicting failure initiation and damage propagation.
