Does anyone have a Mathcad Prime script for rainflow cycle counting for fatigue analysis that they would be willing to share or can anyone point me to an existing respource. I have several spectra I need to convert into stress histograms. The spectra each have more than 20,000 lines of data

Did you try to search this forum for "rainflow". There seem to be some hits - http://communities.ptc.com/message/92957#92957.

BTW, I just noticed you had a question two month ago. Ther were some replies but no reaction from your part!?

Hi,

Please find in attachment "Rainflow Counting" worksheet from the "DynamAssist (Structural Dynamics Toolbox)" e-book for Mathcad, which is available here: http://www.dynamassist.com/ . Another useful discussion: http://communities.ptc.com/thread/19166

This file of Ian Ward is one of the two files from the thread I posted.

That is correct. Only the processed data are different.
