Mechanical and structural components made of lightweight fiber-reinforced composite materials are increasingly being used in mechanical, automotive, aerospace, power generation and transmission including green energy, sporting equipment, recreational, and civil infrastructure engineering applications. However, in vast majority of such applications, applications to static and quasi-static components have been fully developed to the required reliability and safety levels. Also such components have been optimized for high performance. This is not the case with dynamic components. The reason for this limitation is that the dynamic response and associated instabilities of composite components under the time-varying service loadings encountered in such applications have not yet been adequately studied and understood.

由轻质纤维增强复合材料制成的机械和结构部件越来越多地用于机械、汽车、航空航天、发电和传输，包括绿色能源、体育器材、娱乐和土木基础设施工程应用。然而，在绝大多数此类应用中，静态和准静态组件的应用已经完全发展到所需的可靠性和安全性水平。此外，这些组件已经为高性能进行了优化。这与动态组件不同。造成这种限制的原因是，在此类应用中遇到的时变服务负载下，复合组件的动态响应和相关不稳定性尚未得到充分的研究和理解。
