Impact problem - complete part deletion on contact - need help
i am simulating an impact problem. when the part comes in contact, complete part is deleted or disappears. I have attahced the k file. Need help.
It looks like your contact is *Contact_ERODING_surface_to_surface which is probably causing the issue. Is there a reason you are using the eroding part? If not, try *Contact_automatic_surface_to_surface
The screenshot of paper is attached for reference
@harishameed Unfortunately I’m on vacation without a computer so I won’t be able to help as much as I might normally be able to.
Double check that your units are consistent. I saw a pretty wildly high velocity which might make sense for a bullet. Maybe even reduce the velocity substantially and lengthen the simulation time to check that your model is working without that high energy impact. Also try some of these suggestions
Ballistics simulations sound cool and lure a lot of beginners to try to run, but they are not easy to debug due to the complex material models required and the amount of energy present in the impact.
Did you make any progress on getting your model running?
