During the lockdown we decided to take a theoretical look at one of the most commonly used methods of (supposedly) measuring ice adhesion: the Zero Degree Cone Test (ZDCT). Using two cohesive zone models, Kamran and Majid were able to show that most previous measurements were actually incorrect! Perhaps one of the reasons it has taken so long to innovate anti-icing materials is that even measuring their ice adhesion properties is quite difficult. Check it out:
