Baliarsingh, Avaya Kumar (2013) Prediction of fatigue crack propagation life in single edge notched beams using exponential model. MTech thesis.
Metal beams are extensively used in structures, automobile sectors and machine components. Some of their applications include connecting rod of IC engine, shafts, axles, and gears, structures members of bridges and also components of machines. Most of them experience fluctuating or cyclic load condition in their service life‟s such loading conditions may initiate a crack and cause fatigue crack growth. The monitoring and modeling of fatigue crack growth are necessary for the stability and safety of machines and structures. In the present investigation an attempt has been made to develop a fatigue life prediction methodology by using an Exponential Model in single edge notched (SEN) cracked beams. The predicted results are compared with experimental crack growth data. It has been observed that the results obtained from the models are in good agreement with experimental data.
