I try to simulate an impact with a plate and a spherical impactor but I face a problem with interactions. With general contact the analysis is OK. But if I choose surface to surface contact it is like the slave surface (subsurface of the plate) "sticks" to the master surface (impactor surface) as you can see in the picture. Is it possible that this happens because the impactor surface is involved in a rigid body constraint with a reference point or there is no problem with this?
Thanks in advance.
Rigid body constraints have nothing to do with this sticking behavior. What interaction properties you've specified, and also are you allowing the surfaces to initially in contact?
Thanks for the response. The Interaction property is default Hard contact and the interaction is set to the Dynamic,Explicit step not the Initial.
Does this happen during the simulation (then the most probable cause is that you did not allow the surfaces to separate) or at the beginning (then th emost probable cause is that you specified some surface adjustment when defining the interaction or that the default does not work for you).
Thank you Dr. Martin for the response. This happens at the beginning of the analysis.. Can you suggest me a type of interaction property for this situation?
If this happens from teh start check whether nodes are adjusted in the definition of the contact pair (either in the CAE interface or look at the .dat-file). If so, change or remove the adjustment. This has nothing to do with the interaction per se.
