Abaqus Explicit quasi-static stick problem in contact

Abaqus Explicit quasi-static stick problem in contact

(OP)

I am trying to simulate plastic snap behavior against steel locking feature. However, the plastic snap will stick to the steel. It looks that some plastic part nodes are going under steel part nodes, and general contact prevents them coming back... I have used *SURFACE PROPERTY ASSIGNMENT, PROPERTY = FEATURE EDGE CRITERIA but it doesn't solve the problem. Any proposals which could help?

RE: Abaqus Explicit quasi-static stick problem in contact

Can you attach a picture showing this behavior ? What are the settings of the interaction property (normal/tangential behavior) ? Try using contact pairs instead of general contact and refine the mesh of the slave surface to reduce penetrations.

RE: Abaqus Explicit quasi-static stick problem in contact

Also, make sure you have are allowing the parts to separate after contact in the interaction properties.

At least it works now with contact pair definition, thanks!

"Also, make sure you have are allowing the parts to separate after contact in the interaction properties."

I tried to check this from manual, but I didn't find anything related to this. I thought that parts are allowed to separate after contact automatically?

RE: Abaqus Explicit quasi-static stick problem in contact

The default value is for this to be checked. Personally I always create the Normal Behavior and Tangential properties in the contact properties dialog just to be sure.
