Ice-Induced Vibrations
Quantifying the Physical Environment
Research Questions in 2012
• How strong is ice?
• How strong is an ice ridge?
• How does sea ice expand?
• How to model warming permafrost?
Type of Experiments
• Full-scale: in-situ tests, cantilever beam
tests, small-scale uniaxial compression
tests, small-scale indentation tests (bore
hole jack tests) and dynamic test of elastic
properties.
• Scale-model: simulations of scale-model
ice rubble tests, shear box tests
Location of Experiments
• Fjords at Spitsbergen (Norway)
• Barents Sea and Northeast Greenland
waters (KV Svalbard + RV Lance + Oden
cruises)
• HSVA (Germany)
• NTNU (Norway)
Number of Researchers involved: 21
Coastal Technology
Research Questions in 2012
• Understanding Coastal Erosion
• Permafrost Soil Properties
• Sustainable Erosion Protection Systems
Type of Experiments
Full-scale: drilling and penetration tests,
soil sampling and testing of physical and
mechanical properties, temperature and ther-
mal properties of permafrost soils, topograph-
ical measurements, observations of geocryo-
logical structures on thermo-abraded slopes
Location of Experiments
• Vestpynten, the Fjords at Spitsbergen (Norway)
• Baydara, Varandey Island, Pesyakov Island
and the Medynsky Zavorot Peninsula (Russia)
Number of Researchers involved: 9
Ice-Induced Vibrations
Research Questions in 2012
• How to estimate forces from measured structural
displacements (system identification)
• How to simulate the structural behaviour during
ice-induced vibrations (software development)
Main Activity
• Analyses of experiments carried out in 2011 and
development of numerical models.
