Analytical and Case Studies of a Sandwich Structure using Euler-Bernoulli Beam Equation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11)
This paper presents analytical and case studies of sandwich structures. In this study, the Euler-Bernoulli beam equation is solved analytically for a four-point bending problem. Appropriate initial and boundary conditions are specified to enclose the problem. In addition, the balance coefficient is calculated and the Rule of Mixtures is applied. The focus of this study is to determine the effective ...

Study of Acoustics Properties of SK One Component Polyurethane and its Application in Arctic Marine Structures
(Conference object; Konferansebidrag, 2016-12-08)
Marine noise reduction tends to be challenging and requires a comprehensive engineering approach. The soundproofing materials for marine noise reduction are usually exposed to high temperatures, potential fluid or oil spills, engine maintenance and a high airflow environment. This work looks into the acoustic proofing properties of a non-toxic material ‘SK One Component Polyurethane’ developed by ...
Thermal Properties of SK One Component Polyurethane using Experiments and Multiphysics Simulations
(Conference object; Konferansebidrag, 2016-12-08)
This study proposes to determine the thermal conductivity of SK One Component Polyurethane (SKOCP) developed by China Institute of Water Resources & Hydropower Research Beijing IWHR-KHL Co. Ltd. SKOCP provides excellent proof of aging and chemical resistance of this material. It is non-toxic, acts as a good anti-seepage, offers anti-abrasion and good anti-freezing performance. In addition, it has ...
Multiphysics investigation of Ice Adhesion over PVC surface
(Conference object; Konferansebidrag, 2015-12-10)
This work investigates the ice over a PVC (polyvinyl chloride also known as ‘PVC’) surface as a two-layer laminate model. In this study, ice was frozen over a PVC
surface and allowed to adhere. The built samples were tested experimentally in a four-point loading setup. The experimental results contain strain data gathered
through data acquisition system using LabView® software. The data was collected ...
Multiphysicsbased Condition Monitoring of Composite Materials
(Conference object; Konferansebidrag, 2015-12-10)
Composites are increasingly being used in products such as: automobiles, bridges, boats, drillships, offshore platforms, aircrafts and satellites. The increased
usage of these composite materials and the fact that the conditions pertaining to their failure are not fully understood makes it imperative to develop condition
monitoring systems for composite structures.
<br>In this work, we present a ...
Review of the Phenomenon of Ice Shedding from Wind Turbine Blades
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
Wind power is a sustainable source of energy. However, there are certain challenges to be overcome. One of the operational challenges is the phenomenon of ice shedding. Icing happens on wind turbine blades in cold regions. When ice grows to a certain size, it separates from the wind turbine blades resulting in the phenomenon of ice shedding. This phenomenon is of significantly dangerous for equipment ...

Investigation of Ice-PVC separation under Flexural Loading using FEM Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)
This paper presents the FEM technique applied in the study of ice separation over a polyvinyl chloride (PVC) surface. A two layer model of ice and PVC is analysed theoretically using Euler-Bernoulli beam theory and the rule of mixtures. The physical samples are prepared by freezing ice over the PVC surfaces. The samples are tested experimentally in a four-point loading setup. The experimental results ...
Study of Materials’ Impact Properties for Arctic Marine Structures
(Conference object; Konferansebidrag, 2016-12)
It is well understood that sea ice is one of the biggest problems for the safety and reliability of ships and marine structures operating in the Arctic. Specially designed ships, also known as ‘icebreakers’, are usually used to clear ice to make way for merchant and cruise ships. Even then, the ship’s staff must be extremely careful with speed and steering. Heavy impacts of ice result in fatigue and ...
