Arttu Polojärvi
Assistant Professor, Ice Mechanics
Person profile
My research focuses on ice mechanics and Arctic technology. I am interested on the mechanical behavior of sea ice in general and on ice loads on offshore structures. Insight on ice loads is needed for design of safe, efficient and sustainable marine structures for ice-covered seas. I work with computational tools, such as discrete element method, which our group develops for ice mechanics applications. An important part of my work are experiments in laboratory and full-scale for model validation. I perform laboratory scale experiments in cold room and in Aalto Ice Tank . My background is in solid and applied mechanics. I teach topics related to ice mechanics and on applied mechanics.
Person profile
I do research on ice mechanics and Arctic technology. I am interested on the behavior of sea ice floes when they collide with structures or other ice floes, and on the ice loads the floes exert on the structures. Insight on ice loads is needed in the design of safe, efficient and sustainable marine structures for ice-covered seas. The so-called granular behavior of rubble piles of sea ice blocks is especially fascinating for me. I work with computational tools, such as discrete element method, which we develop further for ice mechanics applications with our group. I also like to go to lab and field to perform experiments. My background is in solid and applied mechanics and, in addition to teaching ice mechanics related topics, I like to teach various topics related to these disciplines.
