Abstract

The chain link has failed by overload. There were no evidences of progressive failure like fatigue or stress corrosion cracking. Microstructure and the hardness of the chain link material were found to be satisfactory and no metallurgical abnormalities were responsible for the failure. Evidences suggest that a crack had developed at the weld under shear/bending load followed by which the link had failed by tensile overload. Simulated test showed that if there exists a through crack, the link could fail at a load of 1.6 TF.
