Those warning messages indicate that the solution accuracy is poor. If you look at the Total Deformation result using a display scale factor of 1.0 True Scale, you might even find the solution is complete garbage.

Item #3 is the most telling warning, it is saying something deformed further than the entire dimension of your model! Frictional contact can be tricky to get started. The warnings above imply that the contact was not established and the surfaces may have passed through each other as if no contact was defined. You should be able to see that if you look for it.

The corrective action is to have the following Analysis Settings:

  1. Large Deflection ON
  2. Auto Time Stepping ON
  3. Inital Substeps = 100
  4. Maximum Substep = 1000
  5. Minimum Substeps = 1 unless you are using a nonlinear material model.

Before you solve, insert a Contact Tool under the Connections folder and Generate Initial Contact Status.  Check that the Frictional Contact is Closed.If it is Near Open with a tiny gap, such as 1e-3 or smaller, then you can edit that contact and set the Interface Treatment to Adjust to Touch.

With the above changes, the solution may solve without those warnings and the result should have good accuracy.
