WHAT DESIGNERS SHOULD KNOW ABOUT FRACTURE TOUGHNESS

Is brittle fracture a brand new problem? Brittleness becomes a threat with high strength steels or thicker plates. Only within the past 20 years have we started using these higher strength steels for structures. During the same time, welding has become commonplace and has brought a strong temptation to use thicker plates. In about 90% of the cases involving cracking, if any toughness at all had been specified, trouble would probably have been avoided. Designers or owners should test the steel he gets; steel companies also have an obligation to provide information on steel toughness. They should state the range of fracture toughnesses at given temperatures.
