摘要

In the present study, loading history for ice specimen which is made of fresh water was measured by conducting an ice bending test. In general, ice breaking mechanism in the arctic generates continuous failure. Ice tests were performed using a universal testing machine with three load sensors. The load sensors are used to measure a peak force during the impacts between an inclined plane (jig) and ice specimen. The tests were classified according to the thickness of ice specimen and loading rate. The test scenario was designed by considering the actual interacting situation between an arctic ship and level ice. Three different load cells are fixed to inclined plane of bow structure. In addition, strain rates and ice thickness are considered in order to analyze the mechanical behavior of fresh water ice.
