Ice material properties of ski jumping inruns

The mixture ratio of an ice slurry was determined based on its mixing state and mechanical performance. Both uniaxial compression and beam bending tests were carried out to analyze the effects of ice temperature and loading rates on the compressive and flexural strengths of ice. The damage constitutive model of ice was established and the cracking behavior of ice under different stress conditions was simulated. The main observations are as follows: when the artificial snow proportion was 60 %, the ice slurry had a better mixing state and higher compressive and flexural strengths. The compressive and flexural strengths of ice gradually increased as the ice temperature decreased. In contrast, with the increase in the loading rate, the compressive and flexural strengths of ice first increased and then decreased. The cracking behavior of ice under different stress conditions was accurately simulated by the extended finite element method in ABAQUS.
