Impact modeling of composite aircraft structure

Composite structures are vulnerable to impact damage, and have to satisfy certification

procedures for high velocity impact from bird strike and foreign object damage. Since

performing full scale impact tests is highly expensive and thus impractical, the development of

validated analytical tools for the prediction of the structural response is essential for the

industry to reduce development costs and to speed up the development process. Today, the

capabilities for modeling the initial and progressive failure of composite materials has not been

thoroughly evaluated or validated for commercial finite elements codes. Thus, accurate

modeling of the impact response and failure of composite airframe structures subjected to

impact and crash conditions still remains a challenging problem.

The challenge is then to integrate the knowledge accumulated through various

disciplines such as damage, fracture, computational mechanics, and composite failure

theories to form design methodologies and practical tools that will aid engineers and designers

in the analysis of composite structures.
