Do you know about the capability of Marc to simulate stick-slip friction?
Marc has developed a special algorithm to deal with this type of frictional interaction. I have tested it using a complex model having rubber and metal pieces.
I invite you to test it.
The Marc Mentat User Guide (http://www.marc.com/support/library/ment3_3.pdf) describes the stick-slip algorithm as follows:
Contacting bodies never purely stick; there is always some slip associated with them. The relative sliding velocity indicates the velocity at which they begin to slip.
Using the Stick-Slip friction model, three parameters (a, b, and e) are available to control the numerical behavior. a represents a tolerance on the frictional force before sliding occurs. b represents the amount of relative displacement needed to create slipping conditions. e is a tolerance on the convergence of the solution.
