It's important to insert a Contact Tool under the Connections folder and to generate an initial contact status for the frictional contact. It's possible that the inital status Near or Far.  You want the initial contact status to be Closed.  If it is Near and the gap is very small, you can use Adjust to Touch to close that gap.

It's also important to ramp the load on slowly. That means under Analysis Settings, to turn on Auto Time Stepping and set the Initial Substeps to a large number (or the initial time increment to be very small).

I assume that Large Deflection is already turned on also.
