Tie bonded surfaces
Tie bonded surfaces
(OP)
Hi
What is the best war to tie bonded surfaces like meatal-plate bonded by adhesive to another plate?
I am doing stress analysis no focus on damage or so on.
when I used tie constrain surface to surface, the results do not make sense. Also, you can see the stresses is not continuous on the metal plate and the adhesive layer.
see attached photo please
thanks

RE: Tie bonded surfaces
Tie is the normal method to define a fixed connection between the two surfaces.
RE: Tie bonded surfaces
I am already used Tie but still not what missed to get such a results (the strengthened model has higher stresses in the unpatched face than the model without patch)
Thanks
RE: Tie bonded surfaces
Have you checked that the Tie is actually included? It depends on the settings and the initial positions of the faces. Use the Display Group Manager in Postprocessing and check the node sets that are generated by the solver.
