dc.description.abstract | This paper focuses on with the cyclic plasticity modelling of welded, ex-service P91 material. A multi material model is developed for high temperature cyclic plasticity, including the effects of the three different material zones in the vicinity of the weld: parent metal, weld metal and heat-affected zone. The cyclic plasticity behaviour of the three zones is identified from previously-published high temperature, low cycle fatigue experimental tests on uniaxial parent metal, weld metal and cross-weld (repair weld) specimens on ex-service P91 material. The heat-affected zone is shown to be significantly softer than the parent and weld metals and to act as a focus for concentration of plastic strain, leading to significantly inhomogeneous distributions of stress and strain in the weldment. The multi-material cyclic plasticity model is applied, via a three-dimensional finite element analysis of a welded T-piece header-branch connection, to predict the effects of cyclic internal pressure and small amplitude thermal fluctuations.
