Hi Mom,


A very simple way to think about this is to have two models: one with and one without the void.
It is simple to delete the 6 faces of the void in DesignModeler to end up with a smooth surface.


With the void, I got 643 MPa while without the void, I got 207 MPa, so you could estimate a stress concentration factor of 3.1



Hope this helps. Others may want to comment.


Cheers,
Peter
