主 题:ice adhesion pull-out test shear lag model interfacial shear strength(isS) stress concentration
摘 要:Accurate measurement of the interfacial shear strength between ice and solid surface has important reference significance for the design of anti-icing and de-icing functional *** this paper,a new method is proposed based on the shear lag model of a single fiber pulled out from matrix,in order to accurately determine the interfacial shear strength(ISS)between ice and *** maximum pull-out force at the initiation of interface debonding is well measured in the pull-out test of a metal fiber embedded in an ice matrix.A shear lag model similar to the pull-out test is established and a closed-form relation between the non-uniform interfacial shear stress and the pull-out force is *** the pull-out force reaches its peak value,the ice/metal ISS can be consequently determined as the maximum interfacial shear *** a method takes into account the stress concentration at the interface,which overcomes underestimation of ice/solid ISS based on the apparent strength in previous *** achieved ISS is proven to not only have good convergence,but also be independent of the size and embedded depth of metal *** on the present method,the enhancing effects of freezing temperature and surface roughness on the ice adhesion are further *** present research provides a simple and reliable approach to accurately calibrate the ice/solid ISS,which should be of important reference significance for the design and assessment of anti-icing functional surfaces.
