Fatigue advisor on non linear structural analyses

[aboumrah]

Hello,

I would like to know if someone has been able to made a fatigue analysis (through the fatigue advisor extension), starting from a non linear structural analysis.

I know that it is not allowed by Creo Simulate, and I think that it could be nice to have.

In particular, the description of my problem: I have a static structural analysis on an assembly, with non linear interactions between components; then I'd like to make a fatigue prediction on each single component but unfortunately I cannot use the static structural analysis run on the whole assembly.

Does someone have a suggestion?

Thanks,

Elena

Hi Elena,

Isn't it possible to recreate the stress on the separate parts by creating a static study with the contact pressure from the non-linear study applied as a pressure in the static?  (I agree it would be nice to have this done automatically in some way)

Hi Agnes,

this is a good idea. I also thought about that when I faced the issue.

But the point is: how can you export the contact pressure for each element and then apply it as boundary condition in a subsequent static analysis?

In the past I made the same using Ansys, but I don't know how to reproduce that in Simulate...
