Often machine members subjected to repeated stressing are found to have
failed even when the actual maximum stresses were below the ultimate strength
of the material, and quite frequently at stress values even below the yield
strength. The most distinguishing characteristics is that the
failure had occurred only after the stresses have been repeated a very large
number of times. Hence the failure is called fatigue failure
