The paper presents recent progress on modelling low velocity impact induced damage in fibre reinforced composite laminates. It is important to understand the mechanisms of barely visible impact damage (BVID) and how it affects structural performance. To reduce labour intensive testing, the development of finite element (FE) techniques for simulating impact damage becomes essential and recent effort by the composites research community is reviewed in this work. The FE predicted damage initiation and propagation can be validated by Non Destructive Techniques (NDT) that gives confidence to the developed numerical damage models. A reliable damage simulation can assist the design process to optimise laminate configurations, reduce weight and improve performance of components and structures used in aircraft construction.

模拟低速冲击引起的复合材料层压板的损伤

本文介绍了对纤维增强复合材料层压板中低速冲击引起的损伤进行建模的最新进展。重要的是要了解几乎看不见的冲击破坏（BVID）的机制以及它如何影响结构性能。为了减少劳动密集型测试，模拟冲击破坏的有限元（FE）技术的发展变得至关重要，复合材料研究界最近的工作也在此工作中进行了回顾。有限元预测的损伤的起始和传播可以通过无损技术（NDT）进行验证，该方法可以使已开发的数值损伤模型具有可信度。可靠的损坏模拟可以帮助设计过程优化层压板配置，减轻重量并改善飞机制造中使用的组件和结构的性能。
