For the assessment of welds under high-temperature conditions in the creep or creep-fatigue regimes, the knowledge on the damage location and its temporal evolution are of high importance. The failure behavior of similar welds of ferritic-martensitic

This paper presents the current state of the assessment of similar ferritic-martensitic weld joints in creep or creep-fatigue conditions. Possibilities of the numerical modelling of failure are shown. Two different constitutive models, one for creep

Creep-fatigue behavior at different dwell times was numerically investigated for a 1000 MW steam turbine rotor. Fixed iterations of the startup-running-shutdown process were chosen, and the dwell time of the running phase was changed to study the eff

This study was aimed at identifying the influence of the temperature transient on the creep–fatigue behavior of a steam turbine rotor. Especially, the steam temperature fluctuations during the steady state operation phase could lead the stress to t
