Simulation and Data Mining on Cantilever Box Girder Damage by Explosive Impact

In order to research the damage on weapon equipment by explosive shock wave, simulation experiments were carried out to study explosive impact damage on cantilever box girder. By using principal component analysis (PCA), it presented a data mining method on cantilever box girder damage. It showed that: the calculating result by using this method was agreeable with the result by using traditional method. Therefore, this damage data mining method based on PCA was feasible, it could be used in damage assessment of weapons equipment structure.
