Cyclic loading causes failure of component by fatigue. Due to such cyclic loading cracks formed in component which fails the material before the yield stress. Life of component is more when cyclic loading nature is pure reversible. If magnitude of loading in both directions is different, then means stress plays vital role in fatigue life estimation. Effect of mean stress is proposed by different theories like Morrow rule, SWT relation, and Gerber-Goodman-Soderberg relations. By this theory it is conclude that as increased mean stress reduced the life of component. This paper include above mentioned theory along with numerical justification to theory.
