Creep failure criteria for high temperature alloys
Journal Article
·
· J. Eng. Mater. Technol.; (United States)
The evolution of creep failure criteria is discussed from the early considerations of strain limits to avoid excessive deformation to the current concepts where rupture is used as the basic parameter for most cumulative damage laws. In addition to these modes of failure, the strain to crack initiation itself is considered as a possible overriding criterion for modern cast high temperature resistant alloys where interacting phenomena of creep and fatigue occur.
