Hi Richard,

I am new to fatigue analysis using Caesar-II. One of my contract scope is to design the piping system (B31.3) for a life of 35 years. Since it exceeds the 7000 cycle, so i must consider the fatigue analysis (i.e.)365*35 = 12775 cycles which corresponds to a stress range factor of 0.905. So to consider this effect in the allowable stress range, in Caesar-II where is the provision to enter the stress range factor. If not, am i have to do the fatigue analysis, if so where can i find the stress range factor - figure 302.3.5 in Caesar-II or the fatigue material curve.

Please clarify....
