- Fatigue failure is a mail form of engineering structures, especially for aircraft structures. Crack initiation and propagation threat to flight safety. So far, there has been a variety of methods in fatigue life prediction. Within them, damage mechanics method is a special engineering calculating method. Based on theory of damage mechanics, a new life prediction model for high circle fatigue of metal is proposed. The equation of damage evolution adopted here is concise and efficient, from which the formula for fatigue life prediction under general fatigue load could be given. Consequently, the damage parameter can be determined through standard fatigue experimental data. This new method simplifies the traditional method of life prediction, and reflects the performance of the material fatigue damage concisely and accurately.
