  To perform fatigue analysis on titanium alloy.. the stress life curve is missing in material property .. how to add sn curve in material property or is there any other way to perform fatigue analysis

  What version of ANSYS are you using?
  
  You need to acquire the S-N tabular data, either from an online source or perform your own fatigue testing.
  
  Open Engineering Data, and in the Life category of the Toolbox, drag and drop an S-N Curve onto titanium alloy. Then copy and paste the data into the form. There is a Linear S-N Curve if all you know is the Fatigue Strength Exponent, m (slope) and Fatigue Strength Coefficient, A (intercept) and there is also a Bilinear S-N Curve.
