Mechanical properities of aritificial fine-grained ice

We conducted deformation experiments using artificial polycrystalline ice with and without microparticles. To simulate the deformation mechanism in ice sheets, we used fine-grained ice. Initial grain sizes are 60, 58, and 38 micrometer for pure ice, 0.01 and 0.1 wt.% silica-dispersed ice. The dataset shows the strain rates variations against strain for each sample. Deformation experiments are conducted at stresses between 0.2 and 1.0 MPa and temperatures between -5 and -50 oC.本研究针对含微粒与不含微粒的人工多晶冰开展变形实验。为模拟冰盖内的变形机制，本实验选用细晶冰。纯冰试样的初始晶粒尺寸分别为60、58与38微米；含0.01质量百分比（wt.%）与0.1质量百分比（wt.%）二氧化硅分散相的冰样。本数据集展示了各试样的应变率随应变的变化规律。变形实验的施加应力范围为0.2兆帕（MPa）至1.0兆帕（MPa），实验温度范围为-5 ℃至-50 ℃。
