Flexural dynamic response of monopile foundations under linear wave loads
(Peer reviewed; Journal article, 2020-03)An analytical solution for the dynamic response of submerged slender circular cylindrical structures subjected to linear wave loads is presented. A double Laplace transform with respect to temporal and spatial variables ... -
Design, simulation and production of hydraulic briquette press for metal chips
(Peer reviewed; Journal article, 2019)Removal of metal chips are involved in several industrial production processes that machine from casted parts by various operations such as turning, milling and drilling. In addition to the fact that the chips represent a ... -
Mixed-mode I and II fatigue crack growth retardation due to overload: An experimental study
(Peer reviewed; Journal article, 2019-12)Environmental loads acting on structures usually cause fatigue crack propagation under variable amplitude mixed-mode conditions. In order to better estimate the remaining fatigue life, the fatigue crack growth behaviour ... -
Review and synthesis of a walking machine (Robot) leg mechanism
(Peer reviewed; Journal article, 2019-08)A walking machine (robot) is a type of locomotion that operates by means of legs and/or wheels on rough terrain or flat surface. The performance of legged machines is greater than wheeled or tracked walking machines on an ... -

Investigation of the mechanical properties of Acacia tortilis fiber reinforced natural composite
(Peer reviewed; Journal article, 2020-10)The work presented in this paper is motivated by the fact that use of natural fiber materials for structural and non-structural applications have increased within the last two decades. In addition to the known benefits of ... -
Response sensitivity of a semisubmersible floating offshore wind turbine to different wind spectral models
(Peer reviewed; Journal article, 2020)Previous research on the OC3 spar floating offshore wind turbine (FOWT) has shown the sensitivity of the yaw and side-side modes' load and motion responses to different atmospheric conditions. Using the same baseline turbine ... -
Use of simulator training to mitigate risks in arctic shipping operations
(Peer reviewed; Journal article, 2019)Over the recent years, ship traffic in the polar areas has increased. There is reason to believe that this traffic, and especially the cruise traffic, will increase further as the ice retracts towards the poles. There is ... -
CFD simulations of a suspension bridge deck for different deck shapes with railings and vortex mitigating devices
(Peer reviewed; Journal article, 2019)Aerodynamic response of a single-box suspension bridge girder is investigated using CFD simulations. The importance of including railings and vortex mitigating devices such as guide vanes and a spoiler in the simulations ... -
Design of steel bridge girders against ship forecastle collisions
