Micromechanical finite element modelling of thermo-mechanical fatigue for P91 steels,
(Elsevier, 2016-01-21)
In this paper, the cyclic plasticity and fatigue crack initiation behaviour of a tempered martensitic ferritic steel under thermo-mechanical fatigue conditions is examined by means of micromechanical finite element modelling. ...
An improved unified viscoplastic model for strain-rate sensitivity in high temperature fatigue
(Elsevier ScienceDirect, 2013-11-21)
An improved unified cyclic viscoplastic material model for high temperature fatigue of P91 steel is presented. The primary enhancement over existing models is in relation to strain-rate independence of parameters, for ...
Cyclic thermo-mechanical material modelling and testing of 316 stainless steel
(Elsevier ScienceDirect, 2010-04-20)
A programme of cyclic mechanical testing of a 316 stainless steel, at temperatures of up to 600 C under isothermal conditions, for the identification of material constitutive constants, has been carried out using a ...
Cyclic plasticity of welded P91 material for simple and complex power plant connections
(Elsevier, 2016-02-10)
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 ...
Development of life assessment procedures for power plant headers operated under flexible loading scenarios
(Elsevier ScienceDirect, 2013-12-22)
A finite element methodology for thermo-mechanical fatigue analysis of a subcritical power plant outlet header under realistic loading conditions is presented. The methodology consists of (i) a transient heat transfer ...
