Hydroelastic response of concrete shells during impact on calm water
(Peer reviewed; Journal article, 2023)Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ... -
Hydroelastic response of Froude scaled stiffened steel panels exposed to design-critical wave slamming
(Peer reviewed; Journal article, 2023)Stiffened steel panels of offshore ocean structures may experience violent wave impacts which needs to be accounted for in design. The slamming pressures are often measured in scaled wave tank tests and imposed on finite ... -
Hydrogen Enhanced Fatigue Crack Growth Rates in a Ferritic Fe-3wt%Si Alloy
(Journal article; Peer reviewed, 2018)It is well known that the presence of hydrogen in ferrous materials promotes both static fracture and affect the material fatigue crack growth rates. The latter is often referred to as Hydrogen Enhanced Fatigue Crack Growth ... -
Hydrogen enhanced fatigue crack growth rates in a ferritic Fe-3 wt%Si alloy and a X70 pipeline steel
(Journal article; Peer reviewed, 2019)It is well known that ferrous materials can be damaged by absorption of hydrogen. If a sufficient quantity of hydrogen penetrates into the material, static fracture and the material's fatigue performances can be affected ... -
Hydrogen for maritime application—quality of hydrogen generated onboard ship by electrolysis of purified seawater
(Peer reviewed; Journal article, 2021)Maritime transport is investigating several options to reduce its greenhouse gases and air pollutant emissions. An experimental ship, Energy Observer, is using excess renewable energy to generate onboard hydrogen by ... -
Hydrogen from wet air and sunlight in a tandem photoelectrochemical cell
(Peer reviewed; Journal article, 2019)A solid-state photoelectrochemical (SSPEC) cell is an attractive approach for solar water splitting, especially when it comes to monolithic device design. In a SSPEC cell the electrodes distance is minimized, while the use ... -
Hydrogen Induced Vacancy Clustering and Void Formation Mechanisms at Grain Boundaries in Palladium
(Peer reviewed; Journal article, 2020)Hydrogen has a significant impact on the formation of vacancies, clusters and voids in palladium and other metals. The formation of vacancy-hydrogen complexes in bulk Pd and at Σ3 and Σ5 grain boundaries was investigated ... -
Hydrogen informed Gurson model for hydrogen embrittlement simulation
(Peer reviewed; Journal article, 2019)Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the ... -
