Global and Local Approaches to Creep Crack Initiation and Creep Crack Growth
1991Creep crack initiation and creep crack growth behaviours were studied in two creep ductile materials, an austenitic stainless steel and a low alloy ferritic steel. A number of limitations of the global approach to creep cracking, in which unique correlations between time to initiation or creep crack growth rate and the load-geometry parameter, C*, are ...

Structural assessments of creep crack growth
Nuclear Engineering and Design, 1989Abstract A procedure developed within the CEGB for assessing defective components operating in the creep range is described. The procedure utilises simplified methods based on reference stress techniques to estimate three significant times: the time for failure by continuum damage mechanisms without crack extension, the time for incubation prior to ...

Modelling of Creep Crack Growth
1989Models for describing creep crack growth in terms of linear and non-linear fracture mechanics concepts are presented. When an elastic stress field is preserved at a crack tip it is shown that crack growth rate can be correlated by the stress intensity factor K and when a creep stress distribution is attained by the creep fracture parameter C*.

Creep Crack Growth and Cavitation Damage
1981The paper considers in detail the inter-relation between the macroscopic and microscopic approaches to creep crack growth, and describe the deleterious effects of prior damage on creep crack growth rates.

Some observations on creep crack growth
International Journal of Fracture, 1982Equations for the steady state motion of a crack in a creeping structure are investigated. Although general solutions of these equations are not attempted, it is shown that under certain circumstances particular solutions described by the stress intensity factorK or the stationary creep parameterC* are valid.
