Bonded contacts in hypermesh for abaqus user profile

Recommended Posts

hello,

I want to give frictionless bonded contact between each part. The parts which are bonded together should move simultaneously and should not intersect each other or pass through others after contact begins. eg bones with the articulating surface. (one part is bone and other is articulating surface)

Thank you for your reply. But once I set up freeze contact in hypermesh as OptiStruct Solver, I am not able to export the file suitable for Abaqus solver. because I will be using Abaqus for further simulations.

If you want the surfaces to slide, but not come apart, have a look at the no separation option in the abaqus documentation. It's under   *surface behavior. You can select it in the surface behavior/interaction property in hypermesh. If I understood correctly, it allows for sliding, but keeps the surfaces together once they've come into contact. Let me know if I turn out to be wrong. 

 

If you don't want the surfaces to slide and don't want them to come apart, then use *tie, or select tied and no separation under the surface behavior for the contact pair.

Thank you for your suggestion. I have two situations, one they should slide once they come in contact and for others, they should not slide but should remain glued to each other like single part. But there are initial small gaps between parts (very small like 1mm). so, how should I go for it?

use *clearance and its value between them.
