Ice Mechanics, Loads on Structures and Instrumentation

The course introduces students to problems of ice mechanics and gives experience to work with modern scientific equipment in laboratory and field conditions.


The course includes lectures about basic concepts of continuum mechanics (strain, stresses, equations describing mass, formulations of momentum and energy balance), basic model of continuum mechanics (ideal and viscous fluids, elastic and viscous materials, plastic and viscous-elastic materials, granular materials) and methods of continuum mechanics used for the modelling of thermo-mechanical behaviour of saline and fresh ice itself and ice interactions with engineering structures (rheological models with thermal forcing, conceptions of compressive, tensile and flexural strength, bending deformations of floating ice, models of ice ridging and piling up). The course includes lectures about ISO design standards for the calculation of ice loads on offshore structures.

The course includes laboratory work in UNIS cold laboratory and field work on land fast ice. Lectures about the instrumentation organized before the field works introduce students to the equipment used for the measurements of thermo-mechanical characteristics and strength of fresh and saline ice, ice thickness measurements by electro-magnetic and acoustic methods, high frequency measurements of water temperature and sea current velocities used for the calculation of turbulent heat fluxes to the ice surfaces, measurements of internal stresses and displacements of the ice.

 

During field work the students have the possibility to observe sea ice motions and deformations created by tides, wind and sea currents, observe ice actions on coastal structures and ship. They also will gain experience in working with scientific equipment in Arctic conditions. Finally, the students should be able to formulate models and do numerical simulations of sea ice behaviour and ice-structure interactions and perform field and laboratory tests used for the design of offshore and coastal structures in the Arctic.
