Abstract
The creep parameter, C *, used for characterising the stress and strain rate distributions around a crack tip in a creeping material is calculated for double cantilever beam test-pieces by limit analysis and dimensional analysis techniques. Experimental data are presented on a ½% Cr, ½% Mo, ¼%V steel at 565°C which show that creep crack growth under changing loading conditions can be satisfactorily correlated with this parameter, whereas linear elastic fracture mechanics concepts are unable to cope with history of loading effects. The results are consistent with crack growth occurring by the linking-up of intergranular voids ahead of the main crack tip.
