Hi,
I would like to make fatigue study simulation on my simple 3D model. I know exact parameters for this study:
- compressive load (about 700 N) on upper, flat surface (shown in picture 1)
- fixed constraint on lower, concave surface (shown in picture 2)
- 2 mln cycles (or less if it's not possible)
- material: PMMA or ceramics
- as a result I need information how many cycles can my model wihtstand before it breaks
The problem is that I've never used Fatigue Module and I don't know how to set these parameters in it. I would be very grateful for instructions how to do it.
Thanks and regards,
Michalina

Hi Michalina,
please have a look at our examples in the application library of COMSOL. I would suggest to start with the models in the folder "Fatigue Module -> Stress Based" particularly the files "rim fatigue" and "shaft with fillet". For your convenience, I also attached screenshots to this message to point out the location of these files. This should give you a good starting point to implement your own geometry.
