Homework Statement
Physical understanding about the variation of hoop stresses in a plate with a hole
Homework Equations
I have been reading about the solution of stresses in solution of plate with a hole from here: http://www.fracturemechanics.org/hole.html. I’m unable to physically understand the following:
- How is that the hoop stresses become infinity at theta = + or -90? I’m unable to sense this physically? I understand that there is a hole there but at theta = 0, the hoop stresses are compressive (this also corresponds to the hole position since r = a). I’m unable to sense the two scenarios physically. That is: how the hoop stresses become infinity at r = a and theta = +90 or -90 and the hoop stresses become compressive at theta = 0?
The Attempt at a Solution
The question is to do with physical understanding.
