Abstract: To investigate microstructure in ice deformed under simple shear conditions experiments were performed with artificial polycrystalline ice and natural ice samples form Vatnajökull glacier in Iceland. A new deformation apparatus was tested and results from deformation were compared to literature to validate the method. Boundary conditions for deformation were varied. Experiments were performed at -5°C and -10°C and three strain rates were applied (2.5x10-7 1/s, 1.25x10-6 1/s, 2.5x10-6 1/s). ... more
