Hi,
I am trying to run a fatigue study to estimate life of the product. Static study showed that results are well within in yield value for most of the body with few edges & spots where stress value was much more than yield value. I still need to investigate if those higher stress values are because of stress concentration.Before spending any more time on that, I just wanted to run a fatigue study with existing study to see how results are. When I run the study, I got message which says that stress value in the model is more than that of S-N curve. It is asking me if 1. either to update the S-N curve and continue study or 2. run the study with smallest number of cycles from S-N curve.
Just in case, if those stress values are because of stress concentration, is there any way to manually specify stress intensity (P1-P3) to run the fatigue study?
I attached actual message I got.
thank you,

"Just in case, if those stress values are because of stress concentration, is there any way to manually specify stress intensity (P1-P3) to run the fatigue study?"
what do you mean by manually specify the stress intensity? as in tell it to ignore the high stress?
i believe yo uwill just have to extend the curve to get around this message but would agree it would be nice to have it report "nill" or something similar if the curve doesn't cover cases like this one
