Fracture mechanics is a very useful method of characterizing fracture toughness, fatigue crack growth, or stress-corrosion crack growth behaviour in terms of structural design parameters familiar to the engineer: namely, stress and flaw size. Fracture mechanics is based on a stress analysis and thus does not depend on the use of extensive service experience to translate laboratory results into practical design information as long as the engineer can properly analyse the stresses in a specific structural application, knows the size of the flaws present in the structure, ancfcan measure the toughness of his material. Therefore the development of fracture mechanics offers considerable promise in solving the problem of designing to prevent brittle, fatigue, or stress-corrosion failures in large complex welded structures.
