After performing this experiment, the learner will be able to:

• Understand the concept of fatigue failure in engineering materials.
• Study the behaviour of a material subjected to repeated cyclic loading.
• Determine the endurance limit (fatigue limit) of the given specimen.
• Observe the relationship between cyclic stress and the number of cycles to failure.
• Understand the stages of crack initiation and crack propagation during fatigue.
• Recognize the factors affecting fatigue life, such as stress concentration, surface finish, and loading conditions.
• Appreciate the importance of fatigue analysis in the safe design of engineering components subjected to repeated loading.
