We try to simulate a metal forming process in deal.II, which also requires modelling contact between deformable solid bodies (possibly reducible to one deformable body and rigid tools). Developing a capable and somewhat robust contact formulation itself is challenging. Therefore, I would like to ask whether there is already experience, insights, or existing contact implementations available in deal.II that could be used or adapted.
I am aware of the following contact related implementations: - deal.II step 41 ( https://www.dealii.org/current/doxygen/deal.II/step_41.html) and 42 ( https://www.dealii.org/current/doxygen/deal.II/step_42.html, https://wwwold.mathematik.tu-dortmund.de/papers/FrohneHeisterBangerth2014.pdf), which deal with contact. However, these formulations seem quite specialised and appear to be not easily extendable to the problem at hand (involving friction, large sliding, closing/reopening of contact surfaces, etc.), right? - Further, I came across Maien Hamed's (@maieneuro <https://github.com/maieneuro>) work on an ALE approach including contact (2022/2023: http://hdl.handle.net/11427/36777, https://doi.org/10.1007/s00466-023-02303-0). His contact formulation uses an augmented Lagrangian approach including friction and multi-body contact, appears very capable and seems to be one of the most advanced deal.II contact implementations so far. He was also active in the deal.II Google group and on GitHub. Unfortunately, I cannot get a hold of Maien to discuss the formulation and implementation. Maybe he receives a notification about this topic or if anyone is in contact with Maien, I would be delighted if they could make the connection.

But I am not sure how much can be learned or taken from there into the deal.II world. Contact seems to be a rarity in deal.II. But from the works above, I conclude that it is definitely possible in deal.II, it is just a hell of a lot of work. Further, my research focus is not on contact. So, being able to expand on existing works would be crucial and highly appreciated. I certainly missed works on contact in deal.II above. Please feel free to extend and correct the above list of deal.II contact implementations to provide a summary and overview for the future. A clean and updatable list is available on GitHub (deal.ii issue #17304, https://github.com/dealii/dealii/issues/17304), which I will extend/correct. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
