Hi,

Can you please share the details of your query?

Thanks I didn't realize I made a blank post. Actually Im just trying to figure out the impact force. Im simulating impact collision on a bridge. But sometimes with higher initial velocity I get lower peak force than a lower velocity, should't the force be directly proportional to the velocity? I extract impact force from the target underlying elements (impacting object) because they seem to go back to zero as expected, when extracting from contact underlying the force doesnt seem to go back to zero ( I assume because this for the whole girder and not just the contact region maybe?? Idk, initially thought it will be same from both). I attached some screenshots to help.

Hi,

I think you asked a similar query here: Impact force vs simulating impacts (ansys.com)

Please let me know if you are looking for something else.

No its not the same. I'm asking whether higher velocity would always result in higher peak impact force (this is my thought), but that's not what I observe in my simulation and I'm trying to figure out why.
