Salonen, J, Auerkari, P, Lehtinen, O & Pihkakoski, M 2007, ' Experience on in-service damage in power plant components ', Engineering Failure Analysis, vol. 14, no. 6, pp. 970-977 . https://doi.org/10.1016/j.engfailanal.2006.12.007
Two principal groups of failure mechanisms appear in power plant components. On one hand, each component is usually known to suffer at least potentially from certain failure mechanisms that are expected and largely accounted for in design, manufactur

Structures operating in the creep regime will consume their creep life at a greater rate in locations where the stress state is aggravated by triaxiality constraints. Many structures, such as the welded steam mixer studied here, also have multiple ma
