The constitutive relation derived in our previous work based on the microstructure superposition technique is implemented here for three-phase microstructure configuration to study the mechanical behavior of freeze–thaw soils. Three scenarios were considered for the frozen soils: frozen soil...
The effects of extreme meteorological phenomena covering a vast area may cause a huge failure of a power system. The blackout dated the 8th of April 2008, which took place in the large Polish city Szczecin and the surrounding areas, requires analysis of its causes as well as its direct and...
A methodology for including ice-management in a structural reliability analysis is presented. The approach mainly focuses on how icebreakers or offshore installation disconnection capabilities may alter ice-load distributions and thereby reduce the probability of failure. To demonstrate the...
A ship advancing in level ice will introduce several failure processes to the ice sheet, such as localised crushing and breaking due to bending stresses. The resulting ice fragments will interact with each other, with water and with the hull of the ship. They may rotate, collide, or slide along...
Single-beam upward-looking sonars mounted on British submarines have provided a vast amount of Arctic sea ice thickness data since the early 1970s. In this paper we develop a systematic procedure to estimate the bias introduced in the measurement of the ice draft by the standard procedure of...
Specially designed wireless accelerometers units were used in a series of experiments at the snow chute operated by the SLF at Weissflühjoch (Switzerland) during 2008–2009 winter. The purpose of the experiment was to evaluate the best design and the performance of these innovative instruments...
The phenomenon of “temperature dichotomy”, or anomalous heating of surface water under the ice up to temperatures exceeding 4 °C is known to take place occasionally in solar-heated ice-covered freshwater lakes and has usually been explained by the stabilizing effect of the weak vertical...
The triaxial creep experiment of artificially frozen soil in deep alluvium was performed by a self-developed machine of triaxial creep frozen soil. After analyzing the experiment results, applying parabolic yield criterion for improved viscoplasticity in the Nishihara model, a new creep...
