Hello Friends,

 

I am building a fatigue analysis in which case the damage is super high, i suspect it is because the model is cyclically loading what should be constant preload in another region of the structure i am analyzing.

 

Does anyone have instrucitons on how to seperate a constant load from a cyclic load in a linear static subcase that the fatigue subcase references?

 

Thank you!

Jason

    Hi Jason,

     

    Maybe you can have another FATLOAD with constant load in TABFAT throughout the time?
