Reanalysis of Pressure Patterns and Pressure-Area Curves Considering Resolution of Pressure Measurement Film

Demand for resource development and transportation purpose in the arctic region induced many field tests and laboratory ice crushing tests performed since the 1970s. The main purposes of series of tests were to understand the ice behavior and measure the magnitude of ice load/pressure during ice-structure interaction. Resolution of the data measurement system is one of the important points to analyze the obtained data. The ‘high-resolution’ pressure measurement film was applied to obtain pressure distribution and magnitude of pressure. In a former study, only one optimized resolution was selected considering the quality of plots and effectiveness of the data process. In this study, different resolutions were selected and data process was performed to understand the effect of the resolution. Activated area, total force, pressure distribution and pressure-area curves were analyzed. As a result, optimal resolution was discussed.
