实验室生长的纯冰单晶的裂纹是通过冻结在金属板上并随后冷却而产生的，具有准确的晶体地形学取向。裂缝被认为是平面，平行于冰的基面或棱柱面。对于不同金属和不同取向的冰，测量了冰-金属界面产生裂纹的温度：根据这个温度，在一个简单的弹性模型的基础上，计算了冰的极限强度。与其他作者的结果进行了比较，支持了冰-金属界面存在类液层的假设。这种类似液体的层存在于一个温度范围内，这取决于冰面的晶体取向和表面金属的性质。
Abstract Cracks in laboratory-grown single crystals of pure ice, having accurate crystal-lographic orientation, have been produced by freezing onto metal plates and subsequent cooling. The cracks were seen to be plane surfaces, parallel to the basal or prismatic planes of the ice. The temperature at which the cracks were produced at the ice-metal interface was measured for different metals and different orientations of the ice: from this temperature, on the basis of a simple elastic model, the ultimate strength of ice was calculated. A comparison with the results obtained by other authors supports the hypothesis of the existence of a liquid-like layer at the ice-metal interface. This liquid-like layer exists in a temperature range that depends on the crystallographic orientation of the ice surface and on the nature of the facing metal.
