Prediction of ice shearing performance on aluminum substrate is significant to develop de-icing technology for engineering problems. Ice shearing stress, which involves both adhesion and cohesion, varies with progression of substrate-icing both in temporal and spatial. Thus, study on evolution of both during substrate icing helps comprehensive understanding regularity of shearing performance. In this research, an experiment is designed to measure both ice adhesive and cohesive strength. Afterward, the evolutionary law is discussed with both physical and thermal theories. Experiment results show that substrate icing could be divided into several stage in sequence as “freezing”, “cooling” and “equilibrium”. Both adhesive and cohesive strength increases obviously in the freezing and cooling stage, while finally converges in the equilibrium stage. Such evolution of ice adhesive and cohesive strength are contribute to gradual change of temperature during vertical growing of ice layer. Finally, A model is established to evaluate the adhesive and cohesive strength via given initial temperature, time and position.
