Values of Rayleigh Damping Coefficients in Non-Linear Dynamic Simulation (Aluminium)

I'm working with a model of a rigid catenary. The majority of the pieces are made of aluminium.


I know that I need the frequences in order to calculate propperly the coefficients but I only want an aproximation.


Could someone give me a typical range of this values?


I have tried 2 options:


- Both coefficientes = 0  -------> Very high vibration of the beam


- Both coefficientes = 1 -------> Very low vibration of the beam


Thank you.
