Exploration and recovery of arctic resources involves potential risks to ships and structures from ice loading. This thesis investigates the suitability of using chemical pressure-sensing films for ice-structure interaction experiments. A method of adapting the pressure films for use in laboratory-scale ice crushing experiments is first developed. Using the films, a series of uniaxial crushing tests under a range of factors are performed to develop 2D and 3D pressure maps, pressure-area curves and load histories. The results are analyzed to determine the spatial changes to ice under load and the connection between process and spatial pressure-area curves is investigated. Pressure-area equations are developed to compare the results to past research. The suitability of pressure-films for ice tests is analyzed and improvements for future experiments are suggested.
