Stress at the edge of a hole in a rectangular plate

Stress at the edge of a hole in a rectangular plate

(OP)
Need some help with a stress analysis question.

The question has a flat rectangular plate, with a hole in the middle.

I am given the height and thickness of the plate and the diameter of the hole, the yield stress of the plate and the tensile load it is under.

How do I go about finding the stress on the top edge of the hole?

RE: Stress at the edge of a hole in a rectangular plate

google "stress concentration"

Thanks a lot

RE: Stress at the edge of a hole in a rectangular plate

This is truly an enjoyable problem with FEA if you have it.  I would suggest investigating this problem with variance in hole sizes.  The results are really interesting.

On the other hand, a full closed form solution is available in Roarks Formulae for Stress and Strain.
