This paper presents an application of Equivalent Laminate Modeling (ELM) to predict the effective elastic, thermoelastic, and piezoelectric properties of braided composites. Here, two braided composite configurations were considered: biaxial and triaxial. The present ELM-based modeling was validated through a comparison with analytical unit cell modeling. In addition, a comparison with existing numerical and experimental results is also presented. As importantly, a technique to introduce an undulation effect into ELM using constant undulation angle is newly proposed. The results demonstrated the workability of using ELM to approximate the effective properties of braided composites predicted by considerably more sophisticated methods. An excellent approximation of unit cell analysis results highlights the capability of the proposed ELM with undulation effect.

本文介绍了等效层压模型 (ELM) 在预测编织复合材料的有效弹性、热弹性和压电性能方面的应用。在这里，考虑了两种编织复合结构：双轴和三轴。本基于 ELM 的建模通过与分析单位单元建模的比较得到验证。此外，还介绍了与现有数值和实验结果的比较。同样重要的是，新提出了一种使用恒定波动角将波动效应引入 ELM 的技术。结果证明了使用 ELM 来近似通过更复杂的方法预测的编织复合材料的有效性能的可行性。
