Dear all,
I was wondering if it is possible to do the following in ABAQUS.
1) Run simulation A with specific Boundary conditions.
2) Create a fresh simulation B where the input is the output of simulation A. Here I want to impose a TIE constraint.
3) Run simulation B.
Any suggestions on how this could be done? The reason for this setup lies in the fact that the TIE constraint cannot be deactivated for the intial step. I have two surfaces that are not initially in contact. In simulation A, I bring these two surface into contact and then I would like to apply the TIE constraint in simulation B.
I did extensive search on forums regarding these type of probelems. One suggestion is to apply "Surface-to-Surface" constraint with "rough" fricition, "hard" contact and allowing "no separation" after contact. I did try this approach and I observed that the surfaces separate at the end of the run at some locations (ever so slightly) even with the given constraint. This messes up the stress distributions at the contact interface.
Any suggestion and comments are higly appreciated.
Thanks.
