Generalized Chessboard Structures Whose Effective Conductivities Are Integer Valued
(Journal article; Peer reviewed, 2012)We consider generalized chessboard structures where the local conductivity takes two values 𝑎� and 𝑏�. All integer combinations of 𝑎� and 𝑏� which make the components of effective conductivity matrix integer valued are ... -

Finite element simulation of punch through test using a continuous surface cap model
(Peer reviewed; Journal article, 2015)An attempt has been made to calibrate the material model parameters of the continuous surface cap model with data from punch through tests performed in the Northern Gulf of Bothnia. An axisymmetric finite element model has ... -
Time-dependent spatial distribution of thermal stresses in the ice cover of a small reservoir
(Peer reviewed; Journal article, 2015)Static ice loads (ice actions) are a key design parameter for dams in cold climates. However, their theoretical description is still elusive, introducing uncertainty in design and hindering development of remediation ... -
Smoothed particle hydrodynamics and continuous surface cap model to simulate ice rubble in punch through test
(Peer reviewed; Journal article, 2015)Recent trend in computational mechanics shows considerable development of numerical methods to simulate discrete materials such as ice rubble. Ice rubble has highly nonlinear behavior and to simulate shear properties ... -
Common solutions and challenges to the traverse of sea ice by ships
(Peer reviewed; Journal article, 2015)The specific challenges of ship operations in sea ice-covered waters of the Arctic depend on factors including the purpose of the operation, the capabilities of the ship and equipment available, the degree of situational ... -
Three years of measurements of first year ridges in the Barents sea and Fram strait
(Peer reviewed; Journal article, 2015)During three expeditions in March 2011, March 2012 and April/May 2013 with the Norwegian coastguard vessel “KV Svalbard”, two pressure ridges around Svalbard, one ridge in Fram Strait and three ridges in Olga strait have ... -
Carbon Nanotube Spectrally Selective Solar Absorbers
(Peer reviewed; Journal article, 2015)The use of multi-walled carbon nanotubes (MWCNTs) as spectrally selective solar thermal absorbers (SSA) in solar thermal collectors is presented in this paper. CNT layers were coated by electrophoretic deposition (EPD) on ... -
Reduction of commercial hematite pellet in isothermal fixed bed-experiments and numerical modelling
(Peer reviewed; Journal article, 2016)In the present work, fixed bed reduction experiments were conducted at 1173 K over a range of H2/CO ratios from 0.8 to 2.0 and subsequently modelled numerically. The model consists of two one-dimensional, isothermal and ... -
Electrophoretically deposited carbon nanotube spectrally selective solar absorbers
(Peer reviewed; Journal article, 2016)Three types of carbon nanotubes(CNT) have been investigated regarding their suitability as spectrally selective solar thermal absorbers.The CNT coatings were electrophoretically deposited on aluminum substrates using ...
