static vs dynamic

[abkdt41]

just wondering if someone could explain the difference between a static and dynamic collision is. im trying to model a side impact crash between 2 cars and just wondering why it would not be accurate using a static collision. i.e. applying a static load on the door in an FEA

It isn't static because you have to account for the momentum of the object that is colliding with the door.

Static results would not be appropriate for this analysis.

EDIT: One thing that I have learned over the years of FEA analysis is this: If you are going to take the time to do an FEA analysis be as accurate as practical. IT PAYS OFF.

Thanks
