The residual compressive stresses over the parts surface increases its fatigue sesign. It is expressed usually design of machine elements ppt number greater thanIt is expressed usually a number greater than one: a SF of 1. Mathematically, theoretical or form stress concentration factor, The value of Kt depends upon the material and geometry of the part. This may be due to two reasons.
