Contact modeling by NE/Nastran
Contact modeling by NE/Nastran
(OP)
I have heard that the contact modeling is difficult by NE/Nastran, if you want to determine a friction coefficient. Is it true?
I know it's possible to model the contact such a way that there is no friction or friction is infinite.

RE: Contact modeling by NE/Nastran
As for friction, you just specify the coefficient. Leave the stiffness for stick value blank. The program will calculate the best value. Also in V9 it will allow you to specify a maximum slick displacement just like they do a maximum acceptable penetration displacement.
