Fatigue Failure | Engineering Approach

This is 2nd part of Fatigue failure video lecture series. Here fatigue failure is explained in a practical, engineering point of view. Discussion starts with why actual value of endurance limit is way below ideal endurance limit obtained from R R Moore rotating beam fatigue test. Effect of surface finish, size, reliability and stress concentration on endurance limit is clearly explained. Concept of Modified Goodman diagram is also explained here.
