The aim of this research was to study the residual burst strength, dynamic structural response, and failure mechanism of composite overwrapped pressure vessel (COPV) subjected to low velocity impact by numerically and experimentally. A three-dimensional composite pressure vessel model was developed using Wound composite module (WCM) plugin of Abaqus. The impact response of composite pressure vessels was calculated based on the Hashin progressive damage criteria. The residual burst strength was predicted using maximum strain failure criteria. The COPV was impact tested and the residual burst strength was calculated. The predicted and testing results were compared, and a good correlation was found.

本研究的目的是通过数值和实验研究复合外包裹压力容器（COPV）在低速冲击下的残余爆破强度、动态结构响应和破坏机制。使用 Abaqus 的伤口复合模块 (WCM) 插件开发了三维复合压力容器模型。复合材料压力容器的冲击响应是根据 Hashin 渐进式损坏标准计算的。使用最大应变破坏标准预测残余爆破强度。COPV 进行了冲击测试并计算了残余爆破强度。比较了预测结果和测试结果，发现了良好的相关性。
