This paper studied the contact stresses in curvic attachments.The principal purpose of this research is to employ a method of alleviating the fluctuating hoop stresses which can be considered to be a major contribution to fatigue failure in curvic attachments.This method entails novel precision geometry of the contacting flat on curvic which is a tactic to get appropriate arc heights in in-plane direction as well as vary radius in outof-plane direction.The dimensional finite elements in both directions were analyzed.These analysis results indicated that significant reduction in fluctuating hoop stresses can be achieved by the proposed method,provided that the precision geometry is controlled sufficiently precisely.
