I have a model of a deformable plate with a hole and a bolt that I have modeled as a rigid body.
The rigid body bolt is fixed to the 'ground' by fully restraining the reference point located at its center. The plate is restrained on its far end in z, rx and ry. The corner node on this edge is also restrained in y.
Clearly, there can be no rigid body motion other than x-translation of the plate.
However, I want the plate to move in x and ultimately come into contact with the bolt. I have modeled surface to surface contact between the nodes on the hole boundary (slave region) and the rigid bolt surface (master surface).
My solution does not converge and aborts the analysis. What could be wrong? I have run a data check and found that the COPEN clearance is 1mm everywhere initially, as I desire (I am modeling clearance).
As an aside if I define the master surface incorrectly by selecting the inside of the cylinder rather than the outside, then ABAQUS will adjust the slave nodes to close in exactly on the bolt and I will get a solution. Of course this is not the solution I would like.
The CAE file is available on the below link, any help would be HUGELY appreciated.
