Hello,

 

I am want to carry Fatigue analysis on rubber.

 

I have refer to OS-1340: Fatigue (Stress - Life) Method  using Fatigue Process Manager (FPM) using S-N (Stress - Life)
Method. I am facing this error

 

*** ERROR # 6964 ***
 Subcase 1 referenced in FATLOAD card 11 is neither linear static 
 nor transient subcase. Nonlinear results are not valid for linear 
 superposition. PARAM,NLFAT,YES can be added to bypass this error.
 However it is entirely user's responsibility to make sure the validity 
 of the result under this special usage.

 

 

 

Thanks In Advance

    Hi Teja,

     

    Fatigue is not supported for non-linear material or subcases.
