Dear foamers,

I was wondering about the options for modelling contacts in foam extend and also in solids4foam. I found the FVM approach for this very interesting...

For example, which condition will be the "equivalent" to a bonded contact (like for example in ANSYS Mechanical)?

Thanks a lot in advance

Currently, solids4foam treats contact with a penalty procedure, which is fundamentally similar to the node-to-segment approach from fem. The procedure is suitable for small and large deformations and for rigid-deformable contact.

In bonded contact, bodies are glued and there is no sliding and separation. I think that this behavior can be easily achieved using GGI or AMI, so there is no separate implementation for bonded contact.
