Deformation and Failure of Ice Cover under Compression

  • Jukka Tuhkuri
Part of the Solid Mechanics and Its Applications book series (SMIA, volume 94)

Abstract

Two types of ice cover deformation processes have been studied: compression of ice fields made up of small floes and compression of two identical ice sheets. While these processes have differences, they also show common features. It is suggested that the ice cover deformation should be described as a single process with different phases. In this context, the fact that an ice cover can have several different morphological features (rafted ice, ridges, rubble) is not an indication of different processes, but an indication of different stages in a single process.
