Experimental tests and numerical calculations of replenishment at sea
(Master thesis, 2010)Experimental tests and numerical calculations of replenishment at sea operations for two Fridtjof Nansenclass frigates have been performed. A Fridtjof Nansen-class frigate has been model with the use of empirical formulas ... -
Experimental tests and numerical simulations of ballistic impact on laminated glass
(Peer reviewed; Journal article, 2021)In this study, we investigate double-laminated glass plates under ballistic impact through experimental tests and numerical simulations. The experimental tests are used to determine the ballistic limit velocity and curve ... -
Experimental Tests and Numerical Simulations on the Ballistic Impact Response of a Highly Inhomogeneous Aluminium Foam
(Peer reviewed; Journal article, 2022)A sandwich structure is a composite material consisting of thin skins encapsulating a cellular core. Such structures have proven to be excellent energy absorbents and are frequently found in various types of protection. ... -
Experimental triaxial testing of swelling gouge materials
(Journal article; Peer reviewed, 2019)Adequate rock support in weakness zones that may contain swelling minerals poses one of the main challenges of excavating tunnels in hard rock conditions. Deformations under such conditions are influenced by several factors, ... -
Experimental Validation and Design Review of Wave Loads on Large-Diameter Monopiles
(Master thesis, 2015)The objective of the thesis work was to explore challenges related to ULS wave loading on offshore wind turbines, with special emphasis on large-diameter inertia-dominated monopile foundations. Experimental studies testing ... -
Experimental validation of a time-domain approach for determining sectional loads in a floating wind turbine hull subjected to moderate waves
(Journal article; Peer reviewed, 2017)To achieve cost-effective and reliable structural design of floating wind turbines, efficient and accurate time domain numerical approaches are required to analyse structural responses in design conditions, e.g. wind and ... -
Experimental validation of analytical wake and downstream turbine performance modelling
(Journal article; Peer reviewed, 2018)Wake effects in wind farms can cause significant power losses. In order to reduce these losses layout and control optimization can be applied. For this purpose, simple and fast prediction tools for the wake flow are needed. ... -
Experimental Validation of Angular Velocity Measurements for Wind Turbines Drivetrain Condition Monitoring
(Chapter, 2019)Drivetrain bearings are seen as the most common reason of the wind turbine drivetrain system failures and the consequent downtimes. In this study, the angular velocity error function is used for the condition monitoring ... -
Experimental validation of attitude and rate-sensor bias filter using range-difference measurements
(Peer reviewed; Journal article, 2018)This paper considers the problem of constructing a filter for estimating attitude and rate-sensor bias, that has both proven stability and close-to-optimal performance with respect to noise. The filter is based on measuring ... -
