In this paper the problem of cumulative creep damage is considered.
non-linear creep damage accumulation model, suitable for variable loading
and/or temperature, is presented.
The proposed damage accumulation function
takes into account the previous damage history as well as the loading order
This damage function is specified with respect to damage parameters
derived by the stress versus Larson-Miller parameter curve.
It is shown that
some of the existing models can be obtained as a particular case of the model
developed here in.
Theoretical results are correlated well with experimental
data for austenitic steel X-8-CrNiMoNb-16-16 at 700 °C subjected to a square
Failure of structural and machine components, such as those used in chemical
reactors and power pla...
