A Comparative Study Of Fatigue Failure Due To Acceleration Pulse Loading Over

This research paper deals with experimentation of a circular steel rod with specific geometry, for comparative study of fatigue failure test under constant speed and accelerated pulse speed. Two identical specimens are tested at different loadings for same testing procedure and same mac accelerated speed. It found that the component subjected to accelerated pulse failing earlier than the constant speed loading cycle. In the daily life use 90% of mechanical components are subjected to accele during starting and stopping, applying breaks etc. This process causes to early or sudden failure of component than its fatigue life based on constant speed compared to acceleration
