TAGGED: bonded, shared-topology
February 17, 2021 at 4:13 pmRameez_ul_HaqSubscriberCan anyone torch up my mind by telling me the difference between the shared topology and bonded contact. I mean if I have an option of shared topology, then why would I be using shared topology, and vice versa? Should I expect differences in the stress within and near the same regions which are connected first by shared topology, and then by bonded contact?n
February 17, 2021 at 4:22 pmRameez_ul_HaqSubscriber,I read your comment in an old discussion where you said that you mostly prefer to use the shared topology instead of the bonded. I mean what benefit would we gain by doing that, and if that is possible, then why does even an option exist to use bonded contact?n
February 17, 2021 at 9:10 pmpeteroznewmanSubscribernIs this the old discussion your read? https://forum.ansys.com/discussion/5598/difference-between-bonded-contact-and-node-merge It spells out the benefits of each method. The last paragraph say that you need to use Bonded Contact to study adhesive failure between two bodies using the CZM method.n
February 21, 2021 at 9:52 pmRameez_ul_HaqSubscriber,how can we choose the best contact formulation for our model? I mean if I depend upon 'program controlled' option, then how can I be sure if the ANSYS is using the best possible contact formulation? Are there any guidelines which could direct us to use the best possible contact formulation for our model? What are the pros and pitfalls of each of the contact formulation?n

One way of looking at it might be to say that "Bonded" or "Shared Topology" represents analisys on an assembly of welded componants,...a "Contact" scenario might represents analisys on an assembly of bolted componants,...in "Shared Topology" the "Mesh-Nodes" are shared & they touch at points where the indevidual parts touch,...in "Contact" the "Mesh-Nodes" are not shared?
