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. ...
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 ...
Effect of high-temperature corrosion on the service life of P91 piping in biomass co-firing
(American Society of Mechanical Engineers (ASME), 2016-02-24)
Co-firing biomass with traditional fuels is becoming increasingly relevant to thermal power plant operators due to increasingly stringent regulations on greenhouse gas emissions. It has been found that when biomass is ...
A multi-scale crystal plasticity model for cyclic plasticity and low-cycle fatigue in a precipitate-strengthened steel at elevated temperature
(Elsevier, 2016-12-24)
In this paper, a multi-scale crystal plasticity model is presented for cyclic plasticity and low-cycle fatigue in a tempered martensite ferritic steel at elevated temperature. The model explicitly represents the geometry ...
Fatigue damage characterisation of MarBN steel for high temperature flexible operating conditions
(SAGE Publications, 2016-09-10)
This article is concerned with the high temperature low cycle fatigue behaviour of a new nano-strengthened martensiticferritic steel, MarBN. A range of strain-controlled, low cycle fatigue tests are presented on MarBN at ...
A physically-based creep damage model for effects of different precipitate types
(Elsevier, 2016-10-13)
The development of a new precipitate coarsening continuum damage mechanics (CDM) model to simulate the multi-precipitate strengthening mechanisms present in 9Cr steels under high temperature creep deformation is presented ...
