Brilliant. The last 20s is what I hadn't clocked. This is just what I needed, thanks for uploading

Hi, Thank you for your excellent work. My question is that, is there other assumption as well? Is it valid for MDOF (multi degrees of freedom systems) systems which sinusoids are not smooth? regards.

This may serve as a first-order approximation for thinking about damping, but ultimately the assumption that the level of damping is directly proportional to the amplitude relies on a "smooth" motion. So I would say no, because the damping coefficient is unlikely to be constant.

How can you plot the values of ln(A/A0) if you are dealing with the negative amplitudes, you can’t take Ln of negatives?

We are defining A as the maximum positive amplitude of each swing. If you prefer, you can take the ln of the modulus of A/A0 to yield the same result.

Hi, so this accounts for the fact that damping is exponential right?
