A microstructure informed and mixed-mode cohesive zone approach to simulating hydrogen embrittlement
(Peer reviewed; Journal article, 2022)Hydrogen induced failure under uniaxial tension is simulated in a duplex stainless steel considering microstructural feature of the material. There are three key ingredients in the modelling approach: image processing and ... -
A microstructure-based yield stress and work-hardening model for textured 6xxx aluminium alloys
(Peer reviewed; Journal article, 2016)The plastic properties of an aluminium alloy are defined by its microstructure. The most important factors are the presence of alloying elements in the form of solid solution and precipitates of various sizes, and the ... -
Minority carrier lifetimes in Cz-Si wafers with intentional V-I transitions
(Peer reviewed; Journal article, 2017)A p-type Cz-Si crystal has been pulled with varying pulling speed in order to produce wafers containing two distinct regions; A region with silicon self-interstitial defects, and a vacancy dominated region. Band-to-band ... -
A mixed mode cohesive model for FRP laminates incorporating large scale bridging behaviour
(Peer reviewed; Journal article, 2020)A user defined cohesive material model is implemented in the LS-DYNA finite element code. The model is based on interface properties characterised from DCB specimens loaded with unequal bending moments. Different mode ... -
Mixed proton and electron conducting double perovskite anodes for stable and efficient tubular proton ceramic electrolysers
(Peer reviewed; Journal article, 2019)Hydrogen production from water electrolysis is a key enabling energy storage technology for the large-scale deployment of intermittent renewable energy sources. Proton ceramic electrolysers (PCEs) can produce dry pressurized ... -
Mn promoted Co catalysts for Fischer-Tropsch production of light olefins – An experimental and theoretical study
(Peer reviewed; Journal article, 2018)Three different CoMn/gamma-Al2O3 catalysts were prepared by the incipient wetness impregnation route and compared to a Co/gamma-Al2O3 catalyst. The effect of co-impregnation vs. sequential impregnation as well as the order ... -
Modeling Contact Resistance and Water Transport within a Cathode Liquid-Fed Proton Exchange Membrane Electrolyzer
(Peer reviewed; Journal article, 2023)Conventional proton-exchange membrane (PEM) water electrolyzers use thicker membranes (>175 μm) than their PEM fuel cell counterparts (<25 μm), which reduces hydrogen crossover but also reduces electrolyzer efficiency due ... -
