DELAYED FRACTURE OF HIGH STRENGTH BOLTS USED IN RAILWAY BRIDGES

It has been about 20 years since high-strength bolts came to be used for the railway bridge. During this period a delayed fracture has occurred in some bolts with the tensile strength more than 1.1 GPa. In this review, case studies of delayed fracture and environmental, mechanical and metallurgical factors governing delayed fracture are presented with some comments on the prevention of bolt failures.
