Hello Eng Tips,
I have computed the eigenvalue buckling analysis in Ansys. I have obtained the load multiplier and the deflection. How do I get the stress associated with this loading?
Not the equivalent stress, but the bending stress associated with the buckling loading?

Thank you.

Linear buckling analysis won’t give you real displacements or stresses. If you need their values, run nonlinear buckling simulation (as regular static analysis but with geometric nonlinearity).
 
Also, be very careful if this is a shell structure, like a silo or similar. You will be grossly overestimating the capacity of such structures using an eigenvalue buckling.
