Fatigue limit, also known as endurance limit, is a property of ferrous iron alloys and titanium [1]. It is the constant amplitude (or range) of cyclic stress that can be applied to a material without causing fatigue failure. Other structural materials such as aluminium, do not have a distinct fatigue limit and will eventually fail even from small stress amplitudes. Ferrous in chemistry is a term used for the iron with an oxidation number +2. ...

Cyclic stress in engineering refers is an internal distribution of forces (a stress) that changes over time in a repetitive fashion. ... In materials science, fatigue is the progressive, localised, and permanent structural damage that occurs when a material is subjected to cyclic or fluctuating strains at nominal stresses that have maximum values less than (often much less than) the static yield strength of the material. ... material is the substance or matter from which something is or can be made, or also items needed for doing or creating something. ...
