Abstract:  
Fatigue is the phenomenon of decrease of resistance of the material to repeated loading and failure take place at the value of the stresses well below the ultimate tensile strength of the material. It has been recognised as a distinct mode of failure for at least 150 years and 89 to 90% of the structural failures can be attributed to it. The review deals with the history of developments and failures, causes and remedial measures, the engineering practice and with an investigation.
