The '''alpha-beta model''' is a mathematical equation used to describe the velocity of [[Fatigue (material)|fatigue]] crack growth, da / dN, as a function of a constant amplitude load driving force ΔK where its constants α and β are obtained through a semi-empirical process.

Originally the alpha-beta model was developed and tested from data generated in tests using commercial grade [[Titanium]] and [[Aluminium Alloy]] 2524-T3 both the structural materials of great interest aeronautical.
