Hi,
I'm interested in using the energy-method (rayleigh-quotient) for estimating buckling forces of 1d beams. Is this method valid in all situations, or are there conditions of aplicabillity ?

I don't think there are any buckling methods that are valid in all situations.
At the bare minimum, any buckling method calculation is only valid when:
-the average compressive stress at buckling is less than the yield stress
-the column cross section is not subject to local crippling
-the column is slender enough that geometric (other than x-section) effects don't apply
-the column is in pure compression
