Impact modeling of composite aircraft structures

这是一个在CRIAQ工业驱动项目计划下运行的研究和发展项目。其目的是发展复合材料飞机结构高速冲击响应的设计方法和预测数值模拟方法。重点是开发增强的耐撞性仿真工具以及复合材料和金属飞机的实际故障建模和验证。由于纤维增强复合材料越来越多地用于飞机的主要结构，如机身部分、机翼前缘、机舱、螺旋桨、航空发动机导管和风扇叶片，因此加拿大飞机工业迫切需要纤维增强复合材料。这些部件很容易受到来自鸟类撞击和外来物体的高速冲击，或者来自不同表面的可生存的坠机冲击，这可能对飞机安全构成严重威胁。

This is a research and development project run under the CRIAQ industry driven project scheme. Its aim is to develop design methodologies and predictive numerical simulation methods for the high velocity impact response of composite aircraft structures. The focus is on developping enhanced crashworthiness simulation tools and practical failure modeling and validation for composites and metallic aircraft . It is urgently required by the Canadian aircraft industry since fibre reinforced composite materials are increasingly being used in primary aircraft structures such as fuselage section, wing leading edges, nacelles, propellers and aeroengine ducts and fan blades. These parts are susceptible to high velocity impacts either from bird strike and foreign objects or from shock of survivable crash landings on different surfaces that can pose a serious risk to aircraft safety.
