Summary

The difficulties of extending fracture mechanics concepts to the cracking and fracture of metal components under creep conditions are considered, and the additional complications — both mechanical and metallurgical — which apply to materials under prolonged exposure to elevated temperatures, discussed. The role of notch-rupture testing and features of creep crack initiation and propagation are described, and suggestions made of the form of ‘fracture-toughness’ parameter which might be applicable to fracture at elevated temperatures.
