Abstract
Creep failure generally occurs either by the attenuative loss of area as flow proceeds (geometrical failure) or by the development of internal cavities. The former mechanism dictates the ultimate creep life of a material. Criteria are developed for this upper limit to life for a variety of creep mechanisms. The effects of both primary creep and necking are discussed and a brief comparison is made between failure criteria for cavitation failure and geometrical failure.
