  Hello,
  
  I've been trying to do fatigue analysis for a new new material but it shows an error that "An error occurred inside the FATIGUE module: Invalid or missing stress life curve." Any possible way to resolve this error will be really appreciated.
  
  Thankyou in advance..!

  ANSYS provides few materials with S-N data. Mostly, you have to provide your own data. Do you have the S-N data for AA7075-T651? Once you have that data, which is simply two columns: Cycles and Alternating Stress, open Engineering Data, drag and drop from the Life category the S-N Curve item onto your material, then paste the Cycles and Alternating Stress data into the blank table.
