3D FEA of stress concentration
Dear all,
I am simulating tensile specimens with an elliptical pore(representing a flaw in the material) in the mid-cross section of the specimen. What I am looking for is the stress concentration caused by this pore.
I am simulating this as a 3D specimen under tensile loading only, with 3D, 8-node linear brick elements(1st order). Now my questions are:
1- Is there any analytical solution for such problems(3D with elliptical pore) with which I can compare my FEA results?
2- Should I get a converged value for stress concentration factor as I refine the mesh?
Attached you can see the FE model cut in half.
Thank you in advace for any hints!

Regarding question1: or at
Regarding question1: or at least some kind of approximation method which I can use as a reference to get a sense how correct my FE estimation of stress concentration factor is.
