Strand7 - Fatigue study
Strand7 - Fatigue study
(OP)
Hi again, new to Strand7 i'm afraid. There does not seem to be a large community of users for this package unlike other packages.
Im looking through the help and tut files for a fatigue study explanation. The load is linear, in respect to force and period. What solver should I be using?
Thanks in advance

The link below isn't specific to Strand7, but looks useful:

RE: Strand7 - Fatigue study
There aren't so much fatigue analysis tutorials in the web, because it's quite specific subject in structural analysis. Bishop is a reference in the Vibration Fatigue area and his material is very good.
I recommend to use the book "Fatigue Testing and Analysis, Theory and Practice" from Yung-Li Lee et al (chapter 4) as a reference in fatigue theory for uniaxial fatigue.
The following PDF file shows an example of fatigue analysis in Ansys Workbench.

I hope it can help,
RE: Strand7 - Fatigue study
I have good experience and knowledge of fatigue testing (repeated linear static loading of metallic components, LR ratio = -1 etc.)
I am trying to simulate this in Strand 7. I know how to do this in Ansys but am new to Strand.
So i want to do a linear static study for stress, then simulate this 10^6 times say.

If you can tell us exactly what you want to do in the analysis I can help but at the moment I'd just be guessing.
Also if you have a supported copy of the program it would be worth contacting Strand7 support!

I think the most correct way (and also feasible and economic) is to write a Matlab or Scilab program that uses Strand7 output data to assess the component fatigue life, using multiaxial fatigue criteria.

Anyone looking at doing that (either for fatigue or any other significant post-processing) should have a look at the API. It allows communication between Matlab (don't know about Scilab) and the Strand7 data and results files. It also has modules for Fortran, C, Delphi, VB and VBA, so will work with most popular programming languages, and also a well-known spreadsheet.

RE: Strand7 - Fatigue study
I need to write a fatigue algorithm/program in Matlab (or Scilab) that read the output of Ansys Workbench. Do you know where (websites, pdfs, books, etc) I can find information to do this?
thank you.
