Fatigue Test Experiment

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

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