Abstract

The combined effect of parameters like surface stiffness, topography, and interface size on ice adhesion and its interfacial fracture behavior was studied. Ice adhesion on aluminum and polyurethane with three different surface roughness and two different surface sizes was evaluated experimentally through mode II interfacial fracture tests on a previously formed block of ice. Results showed that, for stiff surfaces the surface roughness increases the adhesion significantly, due to the transition from adhesive to cohesive fracture. Compliant surfaces do not show this transition, in the same roughness scale due to its susceptibility to deformation. The force required to fracture an ice block from stiff surfaces stabilize after a certain length, while compliant surfaces do not show this transition at the length scales studied. The article elucidates the relevance of different parameters and the consideration of size scales for designing low ice adhesion surfaces.

表面粗糙度、硬度和尺寸对冰附着力的影响

研究了表面硬度、形貌和界面尺寸等参数对冰粘附及其界面断裂行为的综合影响。通过对先前形成的冰块进行模式 II 界面断裂测试，对三种不同表面粗糙度和两种不同表面尺寸的铝和聚氨酯的冰附着力进行了实验评估。结果表明，对于坚硬的表面，由于从粘合断裂过渡到内聚断裂，表面粗糙度会显著增加附着力。在相同的粗糙度范围内，顺应性表面由于容易变形，不会出现这种过渡。坚硬表面使冰块断裂所需的力在一定长度后趋于稳定，而顺从表面在所研究的长度尺度上没有出现这种过渡。文章阐明了不同参数的相关性，以及在设计低冰附着力表面时对尺寸尺度的考虑。

期刊介绍： Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere. Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost. Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
