List 3 of the design methods that can be applied to avoid the occurrence of fatigue
Read the following statement regarding the influence of stress amplitude on the fatigue life of a metal material and indicate if it is True or False.
Decreasing the stress amplitude while maintaining the mean stress means that less work or energy is applied to the structure, and thus less damage is caused resulting in a longer fatigue life.
When does the mean stress level affect fatigue crack propagation rates in metal alloys?
