Creep Crack Growth under Complex Loading

open access: yesJournal of ASTM International, 2011
Fitness-for-service assessments of components operating at high temperature often require estimates of creep crack growth in service. Although methods for calculating creep crack growth are given in R5 and other codes, these methods are limited in terms of their range of application and can be over-conservative.

Creep crack growth in ductile, creep-resistant steels

open access: yesInternational Journal of Fracture, 1987
Creep crack growth in two of the commonly used creep-resistant ferritic steels was investigated. Both steels were tested in the as-processed condition and after many years of service in electric power plants. The test temerature was 540°C (in one case also 500°C and 565°C) and test durations ranged from a few days to a year.

Crack Growth under Creep Conditions

Nature, 1970
IN recent years there has been a growing awareness that the techniques of linear elastic fracture mechanics provide a powerful method for quantifying the behaviour of engineering components containing crack-like defects. In the fast fracture of high strength, low toughness materials1 and in fatigue crack growth2, it is now established that data from ...

Creep Crack Growth

1981
A concise review is presented of widely used theories for the quantitative description of the growth of cracks in creeping media. Deficiencies are highlighted of the way in which calculations of component lifetimes have been carried out. New data is presented which overcomes some of the deficiencies, and results are presented of calculated component ...
