I'm trying to make a comparison, between the FEM results that I get from Abaqus, and the analytical solution.
I agree with dr. Nazar Fracture Mechanics can achieve the required goal.
It could be helpful for you to check up handbooks on stress concentration factors, i.e.

Dear Dr. Stanislav Levyakov,
In Peterson's Stress Concentration Factors book, this is what mentioned about this problem: "Stresses around an elliptical hole in a cylindrical shell in tension have been determined by Murthy (1969), Murthy and Rao (1970), and Tingleff (1971)", I already have a paper by Murthy and Rao (1974) named "ON THE STRESS PROBLEM OF LARGE ELLIPTICAL CUTOUTS AND CRACKS IN CIRCULAR CYLINDRICAL SHELLS", but unfortunately I can't follow a lot of discussions provided there. In my problem I simply have a moment (couples acting) on the end of a cylindrical shell that has an elliptical hole, and I'm trying to quantify the stress around the hole.
Dear Dr. Nazar,
The circular tube is made of an aluminum alloy, it's not a concrete solid member it's a shell. This cylindrical shell has an elliptical opening from one side. Thank you.
Dear Dubravka Todorovic,
Thank you very much for your answer. We can use these formulas if and only if, we agree that we have a flat plate. I already have formulas that not taking into account the curvature of the shell, as a factor affecting the stress distribution. That's why these solutions will not be that accurate comparing with the solution in which curvature parameter is involved.
