The term metal fatigue refers to gradual degradation and eventual failure that
occur under loads which vary with time, and which are lower than the static
strength of the metallic specimen, component or structure concerned. The
static strength is the load which causes failure in one application. The loads
responsible are called fatigue loads. These loads are cyclic in nature, but the
cycles are not necessarily all of the same size or clearly discernible. A fatigue
load in which individual cycles can be distinguished is sometimes called a
cyclic load
