Fatigue Cracking and Prevention
Fatigue cracking is a phenomenon that occurs in metals due to repeated load, which can lead to failure at loads considerably below the material’s static strength. It is estimated that approximately 80-90% of failures of machineries is caused by fatigue cracking originating in negligence and poor maintenance.
