I am not a student, but constantly learning Solidworks.

I developed a scenario that is not totally real world but analogous to our products for IP reasons.

Below is a 36" sq. table made out of sheet metal.  It is to support a crate made of wood or plastic that contains metal parts & weighs 600 lbs.

I applied a force load to the table.  After running the simulation, the stresses are located at expected areas & are low enough that this design would seem to be valid for it's stated purpose.

However, if I look at the displacement, the results look unexpected.  "Large" (.05") bulges appear in the table top.  It's the kind of displacement I would expect in a pressure situation rather than having a semi rigid load placed on top.  Of course the wooden or plastic container itself would deform under load, but I don't see it following the displacement pattern show.

So my questions are:

1) Is there a better way to apply the force to the table so that the displacement would be more true to life (assuming these results are not)?

2) Given that the stresses look fine, do I just ignore the displacement results?

3) And do I trust the stress result given the displacement results doesn't seem true to life?

Appreciate your time.  Attached is the pack-and-go file of the simulation, hope I did it right.  SW 2018
