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) ... -
Welding-induced yield strength heterogeneity in X100Q: Modelling and characterisation
Long, D.J.; Devaney, R.J.; Leen, Sean B.; Barrett, Richard A. (Elsevier, 2021-09-14)Yield strength (YS) heterogeneity in X100Q high strength low alloy (HSLA) steel welded joints is a key factor which influences fatigue life performance. The effects of welding-induced microstructural changes are investigated ...
