Abstract: Fracture toughness of single crystal ice was investigated using sharply edge-notched specimens by three point bending at -10℃. The loading rate K1 was about 200 kPa・m1/2/s. The notch of the specimens was made by pressing the edge of a razor blade on the bottom of the saw cut slot. Four types of specimen were used, in which C-axis of the crystal was placed at an angle 0°, 45°(I), 45 °(II), 90 ° respectively to the notch plane. Observation on the patterns of fracture surface relating to the angle θ and y is also described.
