What Are The Three Stages Of Fatigue Failure? There are three stages of fatigue fracture: initiation, propagation, and final rupture. What does fatigue failure look like? A quick analysis of the fracture surface of a fatigue failure will often show features casually referred to as “beach marks”. These indicate the propagation of the failure from

Do Bike Chains Have Infinite Fatigue Life?

Do Bike Chains Have Infinite Fatigue Life? For many metals, including steel and aluminum, no damage occurs once a constant amplitude load drops below the endurance limit (infinite life). This behavior can be represented by a straight line in a logarithmic diagram called S-N curve. Does aluminum have infinite fatigue life? In addition, in the
