Failure analysis of bridle chain used for hoisting in mines

Failure of engineering components due to presence of defects in the material is common. These defects are either present in the material from the casting stage or get developed during subsequent hot working and thermal treatment operations. Identification of the origins of defects is an important task while analyzing failures where pre-existing defects in the material are the causative factors. A case study and stress calculation on failure of bridle chain links is presented in this paper.
