Spur Gear Crack Propagation Path Analysis Using Finite Element Method Ananda Kumar Eriki, Member, IAENG, Ravichandra R, Member, IAENG and Mohd.Edilan Mustaffa  function of time, leading to the evaluation of the life of the Abstract— An effective gear design balances strength, crack to reach their maximum permissible size from safe durability, reliability, size, weight and cost. However operational life of the structure is defined. unexpected gear failure may occur even with adequate gear tooth design. Failure of the engineering structures is caused by Fracture mechanics has developed into a useful discipline crack, which depends on the design and operating conditions and can be avoided by analyzing and understanding the for predicting strength and life of cracked structures. Linear manner it originates. To develop design guidelines to prevent elastic fracture mechanics can be used in damage tolerance failure modes considering gear tooth fracture, by studying the analysis to describe the behavior of crack. The fundamental crack propagation path in a spur gear. Crack propagation assumption of linear elastic fracture mechanics is that the paths are predicted for a variety of gear tooth geometry at crack behavior is determined solely by the values of the various crack initiation location. The effects of gear tooth stress intensity factors which area funct
