Characterisation of LCF performance of X100 weld-joints: Mechanistic yield strength modelling, finite element analyses and DIC testing
Long, D.J.; Devaney, R.J.; O'Donoghue, P.E.; Song, H.; Barrett, R.A.; Leen, Sean B. (Elsevier, 2021-03-26)This paper is concerned with the effect of welding on the fatigue behaviour of X100 material for steel catenary risers. The methodology includes both modelling and experimental characterisation. The modelling combines (i) ... -
The effect of ferrite phases on the micromechanical response and crack initiation in the intercritical heat-affected zone of a welded 9Cr martensitic steel
Li, M.; Sun, F.; Li, D.F.; O'Donoghue, P.E.; Leen, Sean B.; O'Dowd, N.P. (Wiley, 2018-02-08)This paper presents a crystal plasticity model to predict the tensile response and crack initiation in a mixed ferrite-martensite material with a low volume fraction of pro-eutectoid ferrite, representative of a welding-induced ...
