Experimental characterisation and computational modelling for cyclic elastic-plastic constitutive behaviour and fatigue damage of X100Q for steel catenary risers
(Elsevier, 2018-06-21)New higher strength steels are required for deep and ultra-deepwater steel catenary risers (SCRs). In this work, the cyclic elastic-plastic-damage behaviour of X100Q, a candidate next-generation SCR material is experimentally ... -
Experimental characterization and strengthening mechanism of process-structure-property of selective laser melted 316 L
(Elsevier, 2023-03-02)Heat treatment is the most common method to relieve residual stress and to adjust tensile properties in additively manufactured material. However, the well-known strengthening factors (e.g., dislocation density, cellular ... -
Experimental investigation on damage evolution in pre-corroded aluminum alloy 7075-T7651 under fatigue loading
(Elsevier, 2020-09-01)This paper experimentally investigates the fatigue damage evolution in pre-corroded aluminum alloy (AA) 7075-T7651 via digital image correlation (DIC) and scanning electron microscopy (SEM). Three stages of fatigue damage ... -
