An XFEM-Based Methodology for Fatigue Delamination and Permeability in Composites
(2014)
Carbon fibre reinforced polymers (CFRP) are one of the prospective material families being investigated for use in the fuel tanks of future reusable space launch vehicles (RSLVs). The extreme thermo-mechanical loading that ...
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 ...
Effect of welding on microstructure and mechanical response of X100Q bainitic steel through nanoindentation, tensile, cyclic plasticity and fatigue characterisation
(Elsevier, 2020-12-30)
This paper presents an experimental characterisation of fatigue at welded connections for the next-generation high-strength low-alloy offshore riser steel, X100Q. An instrumented girth weld is conducted with a parallel ...
A dislocation mechanics constitutive model for effects of welding-induced microstructural transformation on cyclic plasticity and low-cycle fatigue for X100Q bainitic steel
(Elsevier, 2020-12-14)
This paper presents a physically-based cyclic viscoplasticity model to capture the influence of welding-induced microstructural transformation on the fatigue response of the bainitic high-strength low-alloy steel, X100Q. ...
