Undergrad A*log(b), Separating the two variables
Hi! I have a problem with the following equation: log(D)-b*log(K) = b*log(z)-log(c) I would like to get D and K on one side of the equal to sign, so that: f(D,K) = g(b, c, z) Is this possible? Peter- fettapetta

Analysis of Fatigue due to random vibration
AlephZero: Thenk you, the link is pretty much one method i use to do the analysis but as i told you I'm questioning it. I would like to know why it's possible to not considirate the mean value differences. They do not mention it there, neither is it mentioned by their reference. Even if it...- fettapetta

Analysis of Fatigue due to random vibration
and if some modes are excited? Let's say a white noise. I guess that is hard to make sure that a component will not be excited here?- fettapetta

Analysis of Fatigue due to random vibration
Hi! I'm trying to find a good way to predict fatigue caused by a random vibration (given PSD). I know at least 2 ways of doing it but I'm questioning them both. One of them is using the rain flow count algorithm at a simulated acceleration/time signal to generate a certain amount of...- fettapetta
