Fatigue failure is the formation and propagation of cracks due to a repetitive or cyclic load. Most fatigue failures are caused by cyclic loads significantly below the loads that would result in yielding of the material.Fatigue cracks can also propagate from existing macroscopic cracks, such as weldRead more
