Modelling and verification of creep strain and exhaustion in a welded steam mixer
Abstract
Structures operating in the creep regime will consumetheir creep life at a greater rate in locations where thestress state is aggravated by triaxiality constraints.Many structures, such as the welded steam mixer studiedhere, also have multiple material zones differing inmicrostructure and material properties. The 3-dimensionalstructure as such in addition to interacting materialzones is a great challenge for finite element analysis(FEA), even to accurately pinpoint the critical locationswhere damage will be found. The studied steam mixer, madeof 10CrMo 9-10 steel (P22), has after 100 000 hours ofservice developed severe creep damage in the severalsaddle point positions adjacent to nozzle welds.FE-simulation of long term behaviour of this structurehas been performed taking developing triaxialityconstraints, material zones and primary to tertiary creepregimes into account. The creep strain rate formulationis based on the logistic creep strain prediction (LCSP)model implemented to ABAQUS, including primary, secondaryand tertiary creep. The results are presented using afiltering technique utilising the formulation of rigidplastic deformation for describing and quantifying thedeveloping "creep exhaustion".
