Abstract

The break-up of sea ice in McMurdo Sound has been investigated during two field trips in the fall of 2000 and 2001 via in-situ cyclic loading and fracture experiments. Details regarding the test site, setup and methods used in the in-situ experiments have been reported [1],[2]. A viscoelastic cohesive crack model [3],[4],[5] is being used to model the cracking behaviour observed and measured on 5m and 10m square test specimens [6],[7]. Bilinear stress-separation curves for the different tests are being back-calculated for first-year Antarctic sea ice. The evolution of these curves during crack growth is under investigation.
