In present day the failure of the machine component is about 90% of the failure is because of the fatigue. In present study the failure of the shaft in the yaw gear box is analyzed .As we the shaft is rotating part of the engine it transmit the power from the one part of the engine to another part. It holds the maximum stress. In this case shaft of heat treated component with ultimate tensile strength Su= 2100Mpa is analysis done with ANSYS (FEA) software & compared with the theoretical calculation. There are different methods which are used to predict fatigue life include stress life(S-N), strain Life (E-N) and Linear Elastic Fracture Mechanics (LEFM). In this project study, S-N approach is used to predict fatigue life for out-put shaft. Key words: Shaft, FEA-ANSYS (16.2), SN-curve, Fatigue –life, Fatigue factor of safety, Fatigue damage Cite this Article: Nagaraj S B, Chetan S, Shyamaprasad S, Venugopal Nair, Fatigue Analysis of Out-Put Shaft Subjected to Pure Torsion, International Journal of Mechanical Engineering and Technology 10(4), 2019, pp. 9–16. https://iaeme.com/Home/issue/IJMET?Volume=10&Issue=4 1. INTRODUCTION A shaft has a circular cross section & it is a rotating component used in almost all the machine .It is used to transfer the energy from the one part to another part .A shaft usually not a uniform cross section because it is mounted by the bearing, fly wheels, clutches & other machine
