    • A dislocation-based model for high temperature cyclic viscoplasticity of 9-12Cr steels 

      Barrett, Richard A.; O'Donoghue, Peter E.; Leen, Sean B. (Elsevier ScienceDirect, 2015-06-22)
      A dislocation-based model for high temperature cyclic viscoplasticity in 9–12Cr steels is presented. This model incorporates (i) cyclic softening via decrease in overall dislocation density, loss of low angle boundary ...
    • Predictions of ICHAZ cyclic thermo-mechanical response in GTAW process for 9Cr steels 

      Mac Ardghail, Padraig; Barrett, Richard A.; Harrison, Noel; Leen, Sean B. (ASME The American Society of Mechanical Engineers, 2019-02-25)
      This work is concerned with the development of a modeling framework to predict the effects of tempered–untempered martensite heterogeneity on the thermomechanical performance of welded material. A physically based ...
