Elastic energy from autocorrelation #233

Open sannant opened 2 years ago

sannant commented 2 years ago

I am implementing the elastic energy from the autocorrelation function in PR https://github.com/ContactEngineering/SurfaceTopography/pull/216.

Actually it is from the FD SDRP slope or variance.

https://github.com/ContactEngineering/SurfaceTopography/blob/e0cf91073702c79b15950f3fc54a6dc8ca45f938/SurfaceTopography/Generic/Fractional.py#L56

I have implemented tests on topographies and it works.

@pastewka Which function should I use for the containers? There should be the SDRP slope as well. otherwise I would use the formula with the ACF

Is this now implemented with those integrate functions?

sannant commented 1 year ago

Only the naive way from the averaged function. The more precize brute force summation I have only done it for the PSD.

Okay!
