Introduction
The water motion in the Arctic Ocean is strongly influenced by the ice cover. The
modern state of the economical development in the Arctic seas requires our
knowledge of the ice properties because of the need for navigation in the ice and
especially in the construction of icebreakers. Development of oil and gas industry
and widening of the engineering constructions in the open sea (oil platforms) and in
the shallow coastal regions (bridges) needs the knowledge of the ice properties to
protect these constructions from the ice forcing. This contribution is related to the
field and laboratory research of the ice properties at the present day of technology
and fracture mechanics.
In the terms of fracture mechanics the natural sea ice is a complex material
whose behavior under load is not always predictable with confidence. It applies
both to the qualitative description of ice fracture mechanism (failure pattern) and to
the quantitative estimate of the breaking load. Sea ice is a complex structural
material in view of its specific structure, inhomogeneity and considerable depenM. Karulina ( ✉ ) ⋅ E. Karulin
