WebMar 1, 2024 · For decades, the ice adhesion strength has been defined by measuring the fracture shear load, P f, needed to detach ice with an interfacial area of A ice, or τ ice = P f /A ice. However, this definition is only correct if the fracture is controlled by interfacial strength, not toughness (Golovin et al., 2024). WebWe measured and modeled the adhesion force between an ice surface and a solid sphere (radius, R = 0.8 mm) after they form a contact. The real-world ice adhesion usually involves ice particles interacting with solid surfaces.
