“…Bare aluminum and steel surfaces were tested solely to give reference values of ice adhesion. The ice adhesion strengths for bare Al and steel surfaces are 487 kPa and 714 kPa, which are comparable to the values in other literature 2 51 . Schematic illustrations of the working principles for the ice detachment, the design of the ice adhesion test apparatus, and the method of ice formation are explained in the Supplementary Information Figs S2–5 , respectively.…”

Ice adhesion is mainly dictated by surface properties, and water wettability is frequently correlated with ice adhesion strength. However, these established correlations are limited to high ice adhesion and become invalid when the ice adhesion strength is low. Here we carried out an experimental study to explore the relationships between low ice adhesion strength and room temperature surface properties. A variety of room temperature properties of 22 polymer-based hydrophilic and hydrophobic samples consisting of both low and high ice adhesion surfaces were analysed. The properties investigated include water adhesion force, water wettability, roughness, elastic modulus and hardness. Our results show that low ice adhesion strength does not correlate well with water contact angle and its variants, surface roughness and hardness. Low elastic modulus does not guarantee low ice adhesion, however, surfaces with low ice adhesion always show low elastic modulus. Low ice adhesion (below 60 kPa) of tested surfaces may be determinative of small water adhesion force (from 180 to 270 μN). Therefore, measurement of water adhesion force may provide an effective strategy for screening anti-icing or icephobic surfaces, and surfaces within specific values of water adhesion force will possibly lead to a low ice adhesion.

“…First of all, modeling requires the characteristics of the ice to be known. Many publications [24].. [31] and research projects [32] deal with this research area. For high strain rate (higher than 10 -4 s -1 ), ice exhibits macroscopically brittle behavior [29].…”

“…The main characteristics useful for our case of applications are thus Young's modulus, density, shear and tensile strengths, and critical energy release rate. These characteristics vary considerably [20][21] [24].. [31] depending on the type of ice (glaze or rime), the means used to obtain this ice (freezer or wind tunnel), the type of degradation (cohesive or adhesive), and the interface material. As glaze ice is best known, Tables 1 and 2 summarize the values of the quantities that are used to carry out the numerical applications or simulations for this ice type, in this article.…”

Electromechanical Resonant Ice Protection Systems: Analysis of Fracture Propagation Mechanisms

et al. 2018

Recent research is showing growing interest in low-power electromechanical de-icing systems and, in particular, de-icing systems based on piezoelectric actuators. These systems use the vibrations generated by piezoelectric actuators at resonance frequencies to produce shear stress at the interface between the ice and the support or to produce tensile stress in the ice. This paper provides analytical and numerical models enabling a better understanding of the main de-icing mechanisms of resonant actuation systems. Different possible ice shedding mechanisms involving cohesive and adhesive fractures are analyzed with an approach combining modal, stress and crack propagation analyses. Simple analytical models are proposed to better understand the effects on ice shedding of the type of mode, ice thickness, or frequency with respect to cohesive and adhesive fractures.

“…The SHEAR -a material is failed as shift, the SPALL -a material is failed as a separation, MELTING -internal energy more than energy of fusion, P GAS -internal energy of a material more than energy of sublimation, GAS -the substance is evaporated. Elimination of the evaporated fragments allows simplifying the analysis of a problem [11][12][13][14][15][16][17][18][19][20][21][22]. The areas of light grey color indicate material fusion and the dark areas correspond to a material condition, while its internal energy more than sublimation energy.…”

Abstract. The results of numerical simulations of a compact steel impactor with the aluminum porous shields under high-speed shock loading are presented. The porosity of barrier varies in wide range provided that its mass stays the same, but the impactor has always equal (identical) mass. Here presented the final assessment of the barrier perforation speed depending on its porosity and initial shock speed. The range of initial impact speed varies from 1 to 10 km/s. Physical phenomena such as: destruction, melting, vaporization of a interacting objects are taken into account. The analysis of a shield porosity estimation disclosed that the protection effectiveness of porous shield reveals at the initial impact speed grater then 1.5 km/s, and it increases when initial impact speed growth.
