Is there a way to calculate damping ratio without experimental data or knowing the damping coefficient?

I’m familiar with the experimental methods to determine the damping ratio of a material, but I’m wondering if there’s an alternative way to calculate it using mechanical properties alone.

For example, stiffness (K) can be derived using the formula K= (A*E)/L, where A is the area, E is the modulus of elasticity, and L is the length. I’m curious if there’s a similar approach for damping ratio? Assume we don’t know the Damping Co-efficient or factor.

Hi @sgundu,

I’m not particularly familiar with a workflow for this but I can ask the structural team for further inputs here.

I’ve found this knowledge base article on our website on how to calculate Rayleigh damping coefficients though:

Is it useful?

Best,
Igor
